AlmaLinux 9.6 [TuxCare] Security Update: glib2 / glib2-devel / glib2-doc / glib2-static / glib2-tests Multiple Vulnerabilities (ALMALINUX9.6:CLSA-2026:1771512005)

critical Nessus Plugin ID 360562

Synopsis

The AlmaLinux host is missing one or more security updates.

Description

The AlmaLinux 9.6 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.6:CLSA-2026:1771512005 advisory.

 - A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap corruption, leading to a denial of service or potential code execution via a buffer-underflow in the GVariant parser when processing maliciously crafted input strings. (CVE-2025-14087)

 - A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing malicious file or remote filesystem attribute values. (CVE-2025-14512)

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 ALMALINUX9.6:CLSA-2026:1771512005.
