Description Thibault Guittet 2026-10-08 14:37:49 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A heap buffer overflow vulnerability was found in Eye of GNOME (eog) in the PNG metadata reader component (eog-metadata-reader-png). The flaw exists in the handling of cHRM and gAMA chunk resume state during PNG file parsing. An attacker could exploit this by crafting a malicious PNG file that, when opened by a victim, triggers the overflow, potentially leading to arbitrary code execution or a denial of service.

Sorry, eog-plugins isn't affected.
