Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2025:1763391572 advisory.

- A vulnerability was found in FreeIPA in how the initial implementation of MS-SFU by MIT Kerberos was missing a condition for granting the forwardable flag on S4U2Self tickets. Fixing this mistake required adding a special case for the check_allowed_to_delegate() function: If the target service argument is NULL, then it means the KDC is probing for general constrained delegation rules and not checking a specific S4U2Proxy request. In FreeIPA 4.11.0, the behavior of ipadb_match_acl() was modified to match the changes from upstream MIT Kerberos 1.20. However, a mistake resulting in this mechanism applies in cases where the target service argument is set AND where it is unset. This results in S4U2Proxy requests being accepted regardless of whether or not there is a matching service delegation rule. (CVE-2024-2698)

- A vulnerability was found in FreeIPA in a way when a Kerberos TGS-REQ is encrypted using the client's 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 user's 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 principal's password). (CVE-2024-3183)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages based on the guidance in TuxCare advisory ALMALINUX9.2:CLSA-2025:1763391572.
