CVE-2026-5201 Details
Description
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.
A heap-based buffer overflow vulnerability has been identified in the gdk-pixbuf library's JPEG image loader. This vulnerability arises from improper validation of color component counts when processing specially crafted JPEG images, leading to insufficient memory allocation for pixel data. The flaw can be exploited remotely without user interaction, such as during thumbnail generation, causing application crashes and denial-of-service conditions.
Users are advised to avoid opening or processing untrusted JPEG files. For distributions that include gdk-pixbuf, such as Ubuntu 24.04 LTS, a patched version is available. The fix involves adding a validation check for color component counts in the JPEG loader, which has already been implemented in the latest gdk-pixbuf release.
