Recent Red Hat Cert Manager Security Vulnerabilities
Linux-PAM pam_namespace LPE via Symlink Race
CVE-2025-8941
7.8 - High
- August 13, 2025
A flaw was found in linux-pam. The pam_namespace module may improperly handle user-controlled paths, allowing local users to exploit symlink attacks and race conditions to elevate their privileges to root. This CVE provides a "complete" fix for CVE-2025-6020.
Directory traversal
libxslt Heap Corruption via atype Flag Manipulation
CVE-2025-7425
7.8 - High
- July 10, 2025
A flaw was found in libxslt where the attribute type, atype, flags are modified in a way that corrupts internal memory management. When XSLT functions, such as the key() process, result in tree fragments, this corruption prevents the proper cleanup of ID attributes. As a result, the system may access freed memory, causing crashes or enabling attackers to trigger heap corruption.
Dangling pointer
PAM Namespace Race: Local Priv Escal via Symlinks in linux-pam
CVE-2025-6020
7.8 - High
- June 17, 2025
A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions.
Directory traversal
UAF in libxml2 XPath Parsing via sch:name Path (CVE-2025-49794)
CVE-2025-49794
9.1 - Critical
- June 16, 2025
A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under certain circumstances when the XML schematron has the <sch:name path="..."/> schema elements. This flaw allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the program's crash using libxml or other possible undefined behaviors.
Dangling pointer
Memory Corruption in libxml2 via sch:name -> DoS
CVE-2025-49796
9.1 - Critical
- June 16, 2025
A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to sensitive data being corrupted in memory.
Out-of-bounds Read
Integer Overflow in libarchive RAR Reader Causes Double-Free
CVE-2025-5914
7.8 - High
- June 09, 2025
A vulnerability has been identified in the libarchive library, specifically within the archive_read_format_rar_seek_data() function. This flaw involves an integer overflow that can ultimately lead to a double-free condition. Exploiting a double-free vulnerability can result in memory corruption, enabling an attacker to execute arbitrary code or cause a denial-of-service condition.
Integer Overflow or Wraparound
cert-manager: Denial of Service via Malicious PEM Data
CVE-2024-12401
4.4 - Medium
- December 12, 2024
A flaw was found in the cert-manager package. This flaw allows an attacker who can modify PEM data that the cert-manager reads, for example, in a Secret resource, to use large amounts of CPU in the cert-manager controller pod to effectively create a denial-of-service (DoS) vector for the cert-manager in the cluster.
