Summary

glib2 security update

Details

GLib is a bundle of three (formerly five) low-level system libraries written in C and developed mainly by GNOME. GLib's code was separated from GTK, so it can be used by software other than GNOME and has been developed in parallel ever since.

Security Fix(es):

A vulnerability was discovered in the GDBusServer component of GNOME GLib, related to improper resource shutdown or release. The product does not release or incorrectly releases a resource before it is made available for re-use, leading to resource leakage. An attacker could potentially exploit this vulnerability by sending a large number of requests to GDBusServer, consuming system resources and causing a denial of service.(CVE-2026-15588)

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)
