AIX : Multiple Vulnerabilities (IJ57232)

high Nessus Plugin ID 299693

Synopsis

The remote AIX host is missing a security patch.

Description

The version of AIX installed on the remote host is prior to APAR IJ57232. It is, therefore, affected by multiple vulnerabilities as referenced in the IJ57232 advisory.

 - A flaw was identified in the X.Org X server's X Keyboard (Xkb) extension where improper bounds checking in the XkbSetCompatMap() function can cause an unsigned short overflow. If an attacker sends specially crafted input data, the value calculation may overflow, leading to memory corruption or a crash.
 (CVE-2025-62231)

 - A flaw was discovered in the X.Org X server's X Keyboard (Xkb) extension when handling client resource cleanup. The software frees certain data structures without properly detaching related resources, leading to a use-after-free condition. This can cause memory corruption or a crash when affected clients disconnect. (CVE-2025-62230)

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

Solution

Please apply the appropriate interim fix per APAR IJ57232.
