Doc Text:
A flaw was found in Eye of GNOME (eog). A heap-based buffer overflow exists in the PNG metadata reader due to improper state handling when parsing split metadata chunks. A remote attacker could exploit this flaw by enticing a user into opening a specially crafted PNG file, potentially leading to arbitrary code execution or a Denial of Service (DoS) via application crash.

Description OSIDB Bzimport 2026-10-08 14:28:08 UTC
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.
