CVE-2026-5201: GNOME gdk-pixbuf heap buffer overflow in JPEG loader

CVE-2026-5201 · Severity: high · CVSS 7.5 · Published 2026-03-31

A vulnerability has been identified in gdk-pixbuf, a widely used library for loading and displaying images in Linux environments. By tricking a system into processing a specially crafted JPEG image—such as through automated thumbnail generation—an attacker can cause applications to crash. This can lead to a denial of service, disrupting operations and affecting the availability of systems that rely on this library for image processing.

Technologies: Gnome Gdk-Pixbuf2. Vendors: Gnome.

Technical details

A heap-based buffer overflow vulnerability (CWE-122) exists in the gdk-pixbuf library's JPEG image loader. The flaw is caused by improper validation of color component counts when processing JPEG data. A remote, unauthenticated attacker can exploit this by providing a malicious JPEG image that triggers the overflow during processing (e.g., during thumbnailing or viewing). Successful exploitation results in an application crash, leading to a denial of service (DoS) condition. Security updates have been released by Red Hat and other distributions to address this issue.

Affected products

GNOME gdk-pixbuf2 2.42.12, 2.42.6
