Red Hat Security Advisory: glib2 security update
Two security vulnerabilities have been identified in the GLib library used in Red Hat Enterprise Linux 9. 4 Extended Update Support. The first is a buffer underflow in the GVariant parser that can lead to heap corruption (CVE-2025-14087). The second is an integer overflow in GLib GIO attribute escaping that causes a heap buffer overflow (CVE-2025-14512). These issues affect core components used by applications written in C, including GNOME. Red Hat has released an updated glib2 package to address these vulnerabilities. The update is rated with a moderate security impact. No known exploits are reported in the wild at this time.
