CVE-2026-107651: Eye of GNOME heap-based buffer overflow in PNG metadata reader

CVE-2026-107651 · Severity: medium · CVSS 5.5 · Published 2026-10-08

Eye of GNOME (eog) is a desktop image viewer for Linux. A heap buffer overflow flaw in its PNG metadata parser can be triggered when a user opens a specially crafted PNG file, leading to application crash or potentially arbitrary code execution. An attacker must trick a user into opening a malicious image file to exploit this vulnerability.

Vendors: Gnome.

Technical details

A heap-based buffer overflow exists in the PNG metadata reader due to improper state handling when parsing split metadata chunks (CWE-122). The vulnerability requires user interaction to open a malicious PNG file and is triggered through local parsing of untrusted image data. Confirmed impact is denial of service via application crash; code execution is theoretically possible but unconfirmed.
