Recent Red Hat Ceph Storage Security Vulnerabilities
Docker Moby <29.5.1: Decompression Binary Hijack in /containers/{id}/archive
CVE-2026-41567
7.5 - High
- June 05, 2026
Moby is an open source container framework. In versions prior to 29.5.1 and in moby/moby v2 prior to v2.0.0-beta.14, when a compressed archive is uploaded to a container via `PUT /containers/{id}/archive` or piped through `docker cp -`, the daemon resolves decompression binaries (such as `xz` or `unpigz`) from the container's filesystem rather than the host's due to incorrect ordering of operations. A malicious container image containing a trojanized decompression binary can achieve arbitrary code execution with full daemon privileges, including host root UID and unrestricted capabilities, when a user uploads a compressed (xz or gzip) archive into that container. This issue is fixed in Docker Engine 29.5.1 and moby/moby v2.0.0-beta.14. Workarounds include only running containers from trusted images, using authorization plugins to restrict access to the `PUT /containers/{id}/archive` endpoint, and avoiding piping compressed archives into containers created from untrusted images
DLL preloading
Go crypto/x509 VerifyHostname DNS SAN quadratic overhead
CVE-2026-27145
7.5 - High
- June 02, 2026
(*x509.Certificate).VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name (SAN) entries. This caused strings.Split(host, ".") to execute repeatedly on the same input hostname. With a large DNS SAN list, verification costs scaled quadratically based on the number of SAN entries multiplied by the hostname's label count. Because x509.Verify validates hostnames before building the certificate chain, this overhead occurred even for untrusted certificates.
Unchecked Input for Loop Condition
golang.org/x/net/idna pre-0.55.0 IDN bug allows silent ASCII/Unicode mix
CVE-2026-39821
8.2 - High
- May 22, 2026
The ToASCII and ToUnicode functions incorrectly accept Punycode-encoded labels that decode to an ASCII-only label. For example, ToUnicode("xn--example-.com") incorrectly returns the name "example.com" rather than an error. This behavior can lead to privilege escalation in programs using the idna package. For example, a program which performs privilege checks on the ASCII hostname may reject "example.com" but permit "xn--example-.com". If that program subsequently converts the ASCII hostname to Unicode, it will inadvertently permits access to the Unicode name "example.com".
Improper Validation of Unsafe Equivalence in Input
Auth Bypass in golang.org/x/crypto/ssh <0.52.0
CVE-2026-46595
7.1 - High
- May 22, 2026
Previously, CVE-2024-45337 fixed an authorization bypass for misused ssh server configurations; if any other type of callback is passed other than public key, then the source-address validation would be skipped.
AuthZ
KnownHosts Revocation Check Failure in golang.org/x/crypto/ssh<0.52.0
CVE-2026-42508
7.4 - High
- May 22, 2026
Previously, a revoked 'SignatureKey' belonging to a CA was not correctly checked for revocation. Now, both the 'key' and 'key.SignatureKey' are checked for @revoked.
Improper Certificate Validation
SSH Auth PartialSuccessError Permissions Discarded (golang.org/x/crypto/ssh <0.52.0)
CVE-2026-39828
8.8 - High
- May 22, 2026
When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error.
Improper Preservation of Permissions
go/crypto/ssh CPU DoS via oversized RSA/DSA keys before 0.52
CVE-2026-39829
7.5 - High
- May 22, 2026
The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by unauthenticated clients during public key authentication. RSA moduli are now limited to 8192 bits, and DSA parameters are validated per FIPS 186-2.
Improper Validation of Specified Quantity in Input
Resource Leak in golang.org/x/crypto/ssh <0.52.0 via Global Request Buffers
CVE-2026-39830
7.5 - High
- May 22, 2026
A malicious SSH peer could send unsolicited global request responses to fill an internal buffer, blocking the connection's read loop. The blocked goroutine could not be released by calling Close(), resulting in a resource leak per connection. Unsolicited global responses are now discarded.
Missing Release of Resource after Effective Lifetime
SSH Agent Constraint-Serialization Bug (v<0.52.0)
CVE-2026-39832
8.7 - High
- May 22, 2026
When adding a key to a remote agent constraint extensions such as restrict-destination-v00@openssh.com were not serialized in the request. Destination restrictions were silently stripped when forwarding keys, allowing unrestricted use of the key on the remote host. The client now serializes all constraint extensions. Additionally, the in-memory keyring returned by NewKeyring() now rejects keys with unsupported constraint extensions instead of silently ignoring them.
Improper Preservation of Permissions
golang.org/x/crypto/ssh: CertChecker nil callback panic <0.52.0
CVE-2026-39835
7.5 - High
- May 22, 2026
SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
NULL Pointer Dereference
Recursion Stack Overflow in protobufjs Decoding before 7.5.6/8.0.2
CVE-2026-44289
7.5 - High
- May 13, 2026
protobufjs compiles protobuf definitions into JavaScript (JS) functions. Prior to 7.5.6 and 8.0.2, protobufjs could recurse without a depth limit while decoding nested protobuf data. This affected both skipping unknown group fields and generated decoding of nested message fields. A crafted protobuf binary payload could cause the JavaScript call stack to be exhausted during decoding. This vulnerability is fixed in 7.5.6 and 8.0.2.
Stack Exhaustion
Go net/mail 1.25.x-1.26.3: ParseAddress/Date CPU/Memory Exhaustion
CVE-2026-39820
7.5 - High
- May 07, 2026
Well-crafted inputs reaching ParseAddress, ParseAddressList, and ParseDate were able to trigger excessive CPU exhaustion and memory allocations.
Unchecked Input for Loop Condition
Double-free CVE-2026-33811 via LookupCNAME in Go net (<=1.26.2)
CVE-2026-33811
7.5 - High
- May 07, 2026
When using LookupCNAME with the cgo DNS resolver, a very long CNAME response can trigger a double-free of C memory and a crash.
1341
DoS via consumePhrase in Go net/mail RFC 5322 parsing <1.26.3
CVE-2026-42499
7.5 - High
- May 07, 2026
Pathological inputs could cause DoS through consumePhrase when parsing an email address according to RFC 5322.
Creation of Immutable Text Using String Concatenation
Heap Exhaustion via Unvalidated Len in Prometheus Remote Read (<3.5.3/3.11.3)
CVE-2026-42154
7.5 - High
- May 04, 2026
Prometheus is an open-source monitoring system and time series database. Prior to versions 3.5.3 and 3.11.3, the remote read endpoint (/api/v1/read) does not validate the declared decoded length in a snappy-compressed request body before allocating memory. An unauthenticated attacker can send a small payload that causes a huge heap allocation per request. Under concurrent load this can exhaust available memory and crash the Prometheus process. This issue has been patched in versions 3.5.3 and 3.11.3.
Resource Exhaustion
Prometheus OAuth Client Secret Exposure via /-/config (pre 3.5.3/3.11.3)
CVE-2026-42151
7.5 - High
- May 04, 2026
Prometheus is an open-source monitoring system and time series database. Prior to versions 3.5.3 and 3.11.3, the client_secret field in the Azure AD remote write OAuth configuration (storage/remote/azuread) was typed as string instead of Secret. Prometheus redacts fields of type Secret when serving the configuration via the /-/config HTTP API endpoint. Because the field was a plain string, the Azure OAuth client secret was exposed in plaintext to any user or process with access to that endpoint. This issue has been patched in versions 3.5.3 and 3.11.3.

Apache Thrift 0.23+ Mismatched Memory Mgmt Routines Vulnerability
CVE-2025-48431
7.5 - High
- April 28, 2026
Mismatched Memory Management Routines vulnerability in Apache Thrift c_glib language bindings. This issue affects Apache Thrift: before 0.23.0. Users are recommended to upgrade to version 0.23.0, which fixes the issue. Description: Specially crafted requests can crash an c_glib-based Thrift server with a clean but fatal "free(): invalid pointer" error message.
Mismatched Memory Management Routines
Grafana Tempo Large Limit Memory Allocation DoS
CVE-2026-21728
7.5 - High
- April 24, 2026
Tempo queries with large limits can cause large memory allocations which can impact the availability of the service, depending on its deployment strategy. Mitigation can be done by setting max_result_limit in the search config, e.g. to 262144 (2^18).
Resource Exhaustion
OAuth2 Proxy <7.15.2: XFF-Uri header bypass via reverse-proxy
CVE-2026-40575
8.7 - High
- April 21, 2026
OAuth2 Proxy is a reverse proxy that provides authentication using OAuth2 providers. Versions 7.5.0 through 7.15.1 may trust a client-supplied `X-Forwarded-Uri` header when `--reverse-proxy` is enabled and `--skip-auth-regex` or `--skip-auth-route` is configured. An attacker can spoof this header so OAuth2 Proxy evaluates authentication and skip-auth rules against a different path than the one actually sent to the upstream application. This can result in an unauthenticated remote attacker bypassing authentication and accessing protected routes without a valid session. Impacted users are deployments that run oauth2-proxy with `--reverse-proxy` enabled and configure at least one `--skip-auth-regex` or `--skip-auth-route` rule. This issue is patched in `v7.15.2`. Some workarounds are available for those who cannot upgrade immediately. Strip any client-provided `X-Forwarded-Uri` header at the reverse proxy or load balancer level; explicitly overwrite `X-Forwarded-Uri` with the actual request URI before forwarding requests to OAuth2 Proxy; restrict direct client access to OAuth2 Proxy so it can only be reached through a trusted reverse proxy; and/or remove or narrow `--skip-auth-regex` / `--skip-auth-route` rules where possible. For nginx-based deployments, ensure `X-Forwarded-Uri` is set by nginx and not passed through from the client.
Authentication Bypass by Spoofing
follow-redirects: Auth Header Leak via Cross-Domain Redirects (1.15.x)
CVE-2026-40895
7.5 - High
- April 21, 2026
follow-redirects is an open source, drop-in replacement for Node's `http` and `https` modules that automatically follows redirects. Prior to 1.16.0, when an HTTP request follows a cross-domain redirect (301/302/307/308), follow-redirects only strips authorization, proxy-authorization, and cookie headers (matched by regex at index.js). Any custom authentication header (e.g., X-API-Key, X-Auth-Token, Api-Key, Token) is forwarded verbatim to the redirect target. This vulnerability is fixed in 1.16.0.
Information Disclosure
Code Injection via Type Field in Protobuf.js <8.0.1
CVE-2026-41242
8.8 - High
- April 18, 2026
protobufjs compiles protobuf definitions into JavaScript (JS) functions. In versions prior to 8.0.1 and 7.5.5, attackers can inject arbitrary code in the "type" fields of protobuf definitions, which will then execute during object decoding using that definition. Versions 8.0.1 and 7.5.5 patch the issue.
Code Injection
OpenFGA 0.1.41.13.1: Preshared Key Leak in /playground
CVE-2026-40293
7.5 - High
- April 17, 2026
OpenFGA is an authorization/permission engine built for developers. In versions 0.1.4 through 1.13.1, when OpenFGA is configured to use preshared-key authentication with the built-in playground enabled, the local server includes the preshared API key in the HTML response of the /playground endpoint. The /playground endpoint is enabled by default and does not require authentication. It is intended for local development and debugging and is not designed to be exposed to production environments. Only those who run OpenFGA with `--authn-method` preshared, with the playground enabled, and with the playground endpoint accessible beyond localhost or trusted networks are vulnerable. To remediate the issue, users should upgrade to OpenFGA v1.14.0, or disable the playground by running `./openfga run --playground-enabled=false.`
Information Disclosure
Pyroscope API Secret Key Leak via Tencent COS Backend <1.15.2/1.16.1/1.17.0
CVE-2025-41118
7.5 - High
- April 15, 2026
Pyroscope is an open-source continuous profiling database. The database supports various storage backends, including Tencent Cloud Object Storage (COS). If the database is configured to use Tencent COS as the storage backend, an attacker could extract the secret_key configuration value from the Pyroscope API. To exploit this vulnerability, an attacker needs direct access to the Pyroscope API. We highly recommend limiting the public internet exposure of all our databases, such that they are only accessible by trusted users or internal systems. This vulnerability is fixed in versions: 1.15.x: 1.15.2 and above. 1.16.x: 1.16.1 and above. 1.17.x: 1.17.0 and above (i.e. all versions). Thanks to Théo Cusnir for reporting this vulnerability to us via our bug bounty program.
Incorrect Permission Assignment for Critical Resource
jq libjq buffer overflow in jv_parse_sized() (CVE-2026-39979)
CVE-2026-39979
8.2 - High
- April 13, 2026
jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the jv_parse_sized() API in libjq accepts a counted buffer with an explicit length parameter, but its error-handling path formats the input buffer using %s in jv_string_fmt(), which reads until a NUL terminator is found rather than respecting the caller-supplied length. This means that when malformed JSON is passed in a non-NUL-terminated buffer, the error construction logic performs an out-of-bounds read past the end of the buffer. The vulnerability is reachable by any libjq consumer calling jv_parse_sized() with untrusted input, and depending on memory layout, can result in memory disclosure or process termination. The issue has been patched in commit 2f09060afab23fe9390cce7cb860b10416e1bf5f.
Out-of-bounds Read
NFSv3 rpc.mountd Privilege Escalation via Directory Bypass (CVE-2025-12801)
CVE-2025-12801
6.5 - Medium
- March 04, 2026
A vulnerability was recently discovered in the rpc.mountd daemon in the nfs-utils package for Linux, that allows a NFSv3 client to escalate the privileges assigned to it in the /etc/exports file at mount time. In particular, it allows the client to access any subdirectory or subtree of an exported directory, regardless of the set file permissions, and regardless of any 'root_squash' or 'all_squash' attributes that would normally be expected to apply to that client.
Incorrect Execution-Assigned Permissions
LibPNG 1.6.55-Pre: OOB Read in png_set_quantize() w/ no hist leads to infinite loop
CVE-2026-25646
7 - High
- February 10, 2026
LIBPNG is a reference library for use in applications that read, create, and manipulate PNG (Portable Network Graphics) raster image files. Prior to 1.6.55, an out-of-bounds read vulnerability exists in the png_set_quantize() API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported by the user's display, certain palettes will cause the function to enter into an infinite loop that reads past the end of an internal heap-allocated buffer. The images that trigger this vulnerability are valid per the PNG specification. This vulnerability is fixed in 1.6.55.
Heap-based Buffer Overflow
GnuTLS DoS via oversized SANs in certificates
CVE-2025-14831
5.3 - Medium
- February 09, 2026
A flaw was found in GnuTLS. This vulnerability allows a denial of service (DoS) by excessive CPU (Central Processing Unit) and memory consumption via specially crafted malicious certificates containing a large number of name constraints and subject alternative names (SANs).
Inefficient Algorithmic Complexity
Go net/url: MEM BOMB via Unlimited Query Param Count
CVE-2025-61726
7.5 - High
- January 28, 2026
The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.
Allocation of Resources Without Limits or Throttling
Grafana Dashboard Permissions PrivEsc via API Scope Bypass
CVE-2026-21721
8.1 - High
- January 27, 2026
The dashboard permissions API does not verify the target dashboard scope and only checks the dashboards.permissions:* action. As a result, a user who has permission management rights on one dashboard can read and modify permissions on other dashboards. This is an organizationinternal privilege escalation.
AuthZ
Grafana Goroutine Leak on /avatar/:hash Gravatar Refresh
CVE-2026-21720
7.5 - High
- January 27, 2026
Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel. Sustained traffic with random hashes keeps tripping this timeout, so goroutine count grows linearly, eventually exhausting memory and causing Grafana to crash on some systems.
Resource Exhaustion
GnuTLS Stack Buffer Overflow in PKCS#11 Init Allows DoS/Code Exec
CVE-2025-9820
4 - Medium
- January 26, 2026
A flaw was found in the GnuTLS library, specifically in the gnutls_pkcs11_token_init() function that handles PKCS#11 token initialization. When a token label longer than expected is processed, the function writes past the end of a fixed-size stack buffer. This programming error can cause the application using GnuTLS to crash or, in certain conditions, be exploited for code execution. As a result, systems or applications relying on GnuTLS may be vulnerable to a denial of service or local privilege escalation attacks.
Stack Overflow
Prototype Pollution via _.unset/.omit in Lodash 4.17.22
CVE-2025-13465
8.2 - High
- January 21, 2026
Lodash versions 4.0.0 through 4.17.22 are vulnerable to prototype pollution in the _.unset and _.omit functions. An attacker can pass crafted paths which cause Lodash to delete methods from global prototypes. The issue permits deletion of properties but does not allow overwriting their original behavior. This issue is patched on 4.17.23
Prototype Pollution
PLY 3.11 RCE via unvalidated picklefile in yacc()
CVE-2025-56005
7.8 - High
- January 20, 2026
An undocumented and unsafe feature in the PLY (Python Lex-Yacc) library 3.11 allows Remote Code Execution (RCE) via the `picklefile` parameter in the `yacc()` function. This parameter accepts a `.pkl` file that is deserialized with `pickle.load()` without validation. Because `pickle` allows execution of embedded code via `__reduce__()`, an attacker can achieve code execution by passing a malicious pickle file. The parameter is not mentioned in official documentation or the GitHub repository, yet it is active in the PyPI version. This introduces a stealthy backdoor and persistence risk. NOTE: A third-party states that this vulnerability should be rejected because the proof of concept does not demonstrate arbitrary code execution and fails to complete successfully.
Marshaling, Unmarshaling
pyasn1 <0.6.2: DOS via excessive RELATIVE-OID octets
CVE-2026-23490
7.5 - High
- January 16, 2026
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.2, a Denial-of-Service issue has been found that leads to memory exhaustion from malformed RELATIVE-OID with excessive continuation octets. This vulnerability is fixed in 0.6.2.
Allocation of Resources Without Limits or Throttling
urllib3 v1.22v2.6.3 Redirect Stream Decompress Bomb (preload_content=False)
CVE-2026-21441
7.5 - High
- January 07, 2026
urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source.
Data Amplification
Nodemailer DoS via crafted email header triggers infinite recursion
CVE-2025-14874
7.5 - High
- December 18, 2025
A flaw was found in Nodemailer. This vulnerability allows a denial of service (DoS) via a crafted email address header that triggers infinite recursion in the address parser.
Improper Check or Handling of Exceptional Conditions
Heap Buffer Overread in util-linux setpwnam() (256-byte usernames)
CVE-2025-14104
6.1 - Medium
- December 05, 2025
A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte usernames, specifically within the `setpwnam()` function, affecting SUID (Set User ID) login-utils utilities writing to the password database.
Out-of-bounds Read
Ansible-Collection-Community-General: Info Exposure via Verbose Debug Output
CVE-2025-14010
5.5 - Medium
- December 04, 2025
A flaw was found in ansible-collection-community-general. This vulnerability allows for information exposure (IE) of sensitive credentials, specifically plaintext passwords, via verbose output when running Ansible with debug modes. Attackers with access to logs could retrieve these secrets and potentially compromise Keycloak accounts or administrative access.
Insertion of Sensitive Information into Log File
Glib Heap Buffer Overflow in g_escape_uri_string()
CVE-2025-13601
7.7 - High
- November 26, 2025
A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.
Integer Overflow or Wraparound
Email Parser Vulnerability: Quoted External Address Escapes Recipient
CVE-2025-13033
7.5 - High
- November 14, 2025
A vulnerability was identified in the email parsing library due to improper handling of specially formatted recipient email addresses. An attacker can exploit this flaw by crafting a recipient address that embeds an external address within quotes. This causes the application to misdirect the email to the attacker's external address instead of the intended internal recipient. This could lead to a significant data leak of sensitive information and allow an attacker to bypass security filters and access controls.
Improper Validation of Syntactic Correctness of Input
SSSD AD Kerberos Auth Plugin Flaw Enables Privilege Escalation
CVE-2025-11561
8.8 - High
- October 09, 2025
A flaw was found in the integration of Active Directory and the System Security Services Daemon (SSSD) on Linux systems. In default configurations, the Kerberos local authentication plugin (sssd_krb5_localauth_plugin) is enabled, but a fallback to the an2ln plugin is possible. This fallback allows an attacker with permission to modify certain AD attributes (such as userPrincipalName or samAccountName) to impersonate privileged users, potentially resulting in unauthorized access or privilege escalation on domain-joined Linux hosts.
Improper Privilege Management
CIRCL FourQ RCE via Low-Order Point Injection in Diffie-Hellman
CVE-2025-8556
3.7 - Low
- August 06, 2025

Improper Validation of Specified Type of Input
GnuTLS NULL Deref in figure_common_ciphersuite()
CVE-2025-6395
6.5 - Medium
- July 10, 2025
A NULL pointer dereference flaw was found in the GnuTLS software in _gnutls_figure_common_ciphersuite().
NULL Pointer Dereference
GnuTLS certtool Heap OOB Null Write in Template Parsing – DoS
CVE-2025-32990
6.5 - Medium
- July 10, 2025
A heap-buffer-overflow (off-by-one) flaw was found in the GnuTLS software in the template parsing logic within the certtool utility. When it reads certain settings from a template file, it allows an attacker to cause an out-of-bounds (OOB) NULL pointer write, resulting in memory corruption and a denial-of-service (DoS) that could potentially crash the system.
Heap-based Buffer Overflow
GnuTLS Double-Free in SAN Export Logic (CVE-2025-32988)
CVE-2025-32988
6.5 - Medium
- July 10, 2025
A flaw was found in GnuTLS. A double-free vulnerability exists in GnuTLS due to incorrect ownership handling in the export logic of Subject Alternative Name (SAN) entries containing an otherName. If the type-id OID is invalid or malformed, GnuTLS will call asn1_delete_structure() on an ASN.1 node it does not own, leading to a double-free condition when the parent function or caller later attempts to free the same structure. This vulnerability can be triggered using only public GnuTLS APIs and may result in denial of service or memory corruption, depending on allocator behavior.
Double-free
GnuTLS CT SCT Heap-Buffer-Overread (CVE-2025-32989)
CVE-2025-32989
5.3 - Medium
- July 10, 2025
A heap-buffer-overread vulnerability was found in GnuTLS in how it handles the Certificate Transparency (CT) Signed Certificate Timestamp (SCT) extension during X.509 certificate parsing. This flaw allows a malicious user to create a certificate containing a malformed SCT extension (OID 1.3.6.1.4.1.11129.2.4.2) that contains sensitive data. This issue leads to the exposure of confidential information when GnuTLS verifies certificates from certain websites when the certificate (SCT) is not checked correctly.
Improper Certificate Validation
systemd-coredump CRASH Race Enables SUID Dump Credential Leak
CVE-2025-4598
4.7 - Medium
- May 30, 2025
A vulnerability was found in systemd-coredump. This flaw allows an attacker to force a SUID process to crash and replace it with a non-SUID binary to access the original's privileged process coredump, allowing the attacker to read sensitive data, such as /etc/shadow content, loaded by the original process. A SUID binary or process has a special type of permission, which allows the process to run with the file owner's permissions, regardless of the user executing the binary. This allows the process to access more restricted data than unprivileged users or processes would be able to. An attacker can leverage this flaw by forcing a SUID process to crash and force the Linux kernel to recycle the process PID before systemd-coredump can analyze the /proc/pid/auxv file. If the attacker wins the race condition, they gain access to the original's SUID process coredump file. They can read sensitive content loaded into memory by the original binary, affecting data confidentiality.
Signal Handler Race Condition
serialize-javascript XSS via unsanitized regex input
CVE-2024-11831
5.4 - Medium
- February 10, 2025
A flaw was found in npm-serialize-javascript. The vulnerability occurs because the serialize-javascript module does not properly sanitize certain inputs, such as regex or other JavaScript object types, allowing an attacker to inject malicious code. This code could be executed when deserialized by a web browser, causing Cross-site scripting (XSS) attacks. This issue is critical in environments where serialized data is sent to web clients, potentially compromising the security of the website or web application using this package.
XSS
OpenSSH Race Condition leading to RCE, known as regreSSHion
CVE-2024-6387
8.1 - High
- July 01, 2024
A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period.
