Recent Red Hat Enterprise Linux Aus Security Vulnerabilities
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
An out-of-bounds memory access flaw was found in the X.Org server
CVE-2024-0229
7.8 - High
- February 09, 2024
An out-of-bounds memory access flaw was found in the X.Org server. This issue can be triggered when a device frozen by a sync grab is reattached to a different master device. This issue may lead to an application crash, local privilege escalation (if the server runs with extended privileges), or remote code execution in SSH X11 forwarding environments.
Memory Corruption
A vulnerability was found in insights-client
CVE-2023-3972
7.8 - High
- November 01, 2023
A vulnerability was found in insights-client. This security issue occurs because of insecure file operations or unsafe handling of temporary files and directories that lead to local privilege escalation. Before the insights-client has been registered on the system by root, an unprivileged local user or attacker could create the /var/tmp/insights-client directory (owning the directory with read, write, and execute permissions) on the system. After the insights-client is registered by root, an attacker could then control the directory content that insights are using by putting malicious scripts into it and executing arbitrary code as root (trivially bypassing SELinux protections because insights processes are allowed to disable SELinux system-wide).
Exposure of Resource to Wrong Sphere
A vulnerability was found in X.Org
CVE-2023-0494
7.8 - High
- March 27, 2023
A vulnerability was found in X.Org. This issue occurs due to a dangling pointer in DeepCopyPointerClasses that can be exploited by ProcXkbSetDeviceInfo() and ProcXkbGetDeviceInfo() to read and write into freed memory. This can lead to local privilege elevation on systems where the X server runs privileged and remote code execution for ssh X forwarding sessions.

A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7
CVE-2020-10711
5.9 - Medium
- May 22, 2020
A NULL pointer dereference flaw was found in the Linux kernel's SELinux subsystem in versions before 5.7. This flaw occurs while importing the Commercial IP Security Option (CIPSO) protocol's category bitmap into the SELinux extensible bitmap via the' ebitmap_netlbl_import' routine. While processing the CIPSO restricted bitmap tag in the 'cipso_v4_parsetag_rbm' routine, it sets the security attribute to indicate that the category bitmap is present, even if it has not been allocated. This issue leads to a NULL pointer dereference issue while importing the same category bitmap into SELinux. This flaw allows a remote network user to crash the system kernel, resulting in a denial of service.
NULL Pointer Dereference
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker
CVE-2019-9506
8.1 - High
- August 14, 2019
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing.

CVE-2018-13405
7.8 - High
- July 06, 2018
The inode_init_owner function in fs/inode.c in the Linux kernel through 3.16 allows local users to create files with an unintended group ownership, in a scenario where a directory is SGID to a certain group and is writable by a user who is not a member of that group. Here, the non-member can trigger creation of a plain file whose group ownership is that group. The intended behavior was that the non-member can trigger creation of a directory (but not a plain file) whose group ownership is that group. The non-member can escalate privileges by making the plain file executable and SGID.
