AlmaLinux 9.2 [TuxCare] Security Update: glib2 / glib2-devel / glib2-doc / glib2-static / glib2-tests (ALMALINUX9.2:CLSA-2026:1789206553)

high Nessus Plugin ID 362175

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.2 host has packages installed that are affected by a vulnerability as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1789206553 advisory.

 - A flaw was found in xdgmime. A heap-based buffer overflow can be triggered in
 _xdg_mime_magic_parse_magic_line() in the xdgmimemagic.c file on little-endian systems when an attacker- controlled MIME magic file in a user-writable XDG data location (e.g., in the $XDG_DATA_HOME/mime/magic path) is parsed by an application performing MIME type detection (e.g., via g_content_type_guess()). When performing byte-swap, incorrect pointer arithmetic on the write side causes an out-of-bounds write of 2 bytes, resulting in an application crash or memory corruption. (CVE-2026-16118)

Note that Nessus has not tested for this issue 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-2026:1789206553.
