CVE-2026-5201 (GCVE-0-2026-5201)

Vulnerability from cvelistv5 – Published: 2026-03-31 08:32 – Updated: 2026-03-31 13:46

Title

Gdk-pixbuf: gdk-pixbuf: denial of service via heap-based buffer overflow when processing a specially crafted jpeg image

Summary

A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.

Severity ?

7.5 (High)
