CVE-2026-107651
Description
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.
Statement
This vulnerability is rated as Moderate impact for Red Hat products because successful exploitation requires user interaction to open a maliciously crafted image file within the desktop image viewer. Although parsing corrupted metadata could theoretically result in memory corruption or arbitrary code execution, execution is constrained to the privileges of the active desktop user and cannot be triggered automatically without direct user involvement. Furthermore, server deployments running headless or without graphical desktop environments installed are not exposed to this flaw.
Mitigation
No mitigation is available for this flaw.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
