Red Hat Security Advisory: glib2 security update
Red Hat has issued a moderate severity security advisory for glib2 addressing two vulnerabilities: a buffer underflow in the GVariant parser (CVE-2025-14087) that leads to heap corruption, and an integer overflow in GLib GIO attribute escaping (CVE-2025-14512) causing a heap buffer overflow. These issues affect Red Hat Enterprise Linux 8. 8 and related update services. The advisory provides updated packages to remediate these vulnerabilities. No known exploits in the wild have been reported. Users of affected Red Hat products should apply the available updates as detailed in the vendor advisory.
