Recent Red Hat Enterprise Linux Eus Security Vulnerabilities

A vulnerability was found in Podman, Buildah, and CRI-O

CVE-2024-9676 6.5 - Medium - October 15, 2024

A vulnerability was found in Podman, Buildah, and CRI-O. A symlink traversal vulnerability in the containers/storage library can cause Podman, Buildah, and CRI-O to hang and result in a denial of service via OOM kill when running a malicious image using an automatically assigned user namespace (`--userns=auto` in Podman and Buildah). The containers/storage library will read /etc/passwd inside the container, but does not properly validate if that file is a symlink, which can be used to cause the library to read an arbitrary file on the host.

Directory traversal

A vulnerability was found in Buildah

CVE-2024-9675 7.8 - High - October 09, 2024

A vulnerability was found in Buildah. Cache mounts do not properly validate that user-specified paths for the cache are within our cache directory, allowing a `RUN` instruction in a Container file to mount an arbitrary directory from the host (read/write) into the container as long as those files can be accessed by the user running Buildah.

Directory traversal

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.

Race Condition

A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the clients session key

CVE-2024-3183 8.1 - High - June 12, 2024

A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the clients session key. This key is different for each new session, which protects it from brute force attacks. However, the ticket it contains is encrypted using the target principal key directly. For user principals, this key is a hash of a public per-principal randomly-generated salt and the users password. If a principal is compromised it means the attacker would be able to retrieve tickets encrypted to any principal, all of them being encrypted by their own key directly. By taking these tickets and salts offline, the attacker could run brute force attacks to find character strings able to decrypt tickets when combined to a principal salt (i.e. find the principals password).

Use of Password Hash With Insufficient Computational Effort

A flaw was found in Booth, a cluster ticket manager

CVE-2024-3049 5.9 - Medium - June 06, 2024

A flaw was found in Booth, a cluster ticket manager. If a specially-crafted hash is passed to gcry_md_get_algo_dlen(), it may allow an invalid HMAC to be accepted by the Booth server.

A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements

CVE-2023-42669 6.5 - Medium - November 06, 2023

A vulnerability was found in Samba's "rpcecho" development server, a non-Windows RPC server used to test Samba's DCE/RPC stack elements. This vulnerability stems from an RPC function that can be blocked indefinitely. The issue arises because the "rpcecho" service operates with only one worker in the main RPC task, allowing calls to the "rpcecho" server to be blocked for a specified time, causing service disruptions. This disruption is triggered by a "sleep()" call in the "dcesrv_echo_TestSleep()" function under specific conditions. Authenticated users or attackers can exploit this vulnerability to make calls to the "rpcecho" server, requesting it to block for a specified duration, effectively disrupting most services and leading to a complete denial of service on the AD DC. The DoS affects all other services as "rpcecho" runs in the main RPC task.

A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory

CVE-2023-3961 9.8 - Critical - November 03, 2023

A path traversal vulnerability was identified in Samba when processing client pipe names connecting to Unix domain sockets within a private directory. Samba typically uses this mechanism to connect SMB clients to remote procedure call (RPC) services like SAMR LSA or SPOOLSS, which Samba initiates on demand. However, due to inadequate sanitization of incoming client pipe names, allowing a client to send a pipe name containing Unix directory traversal characters (../). This could result in SMB clients connecting as root to Unix domain sockets outside the private directory. If an attacker or client managed to send a pipe name resolving to an external service using an existing Unix domain socket, it could potentially lead to unauthorized access to the service and consequential adverse events, including compromise or service crashes.
