A flaw was found in Matthias-Wandel jhead. This vulnerability, a heap-based buffer overflow, exists within the WebP EXIF Handler component, specifically in the `ProcessGpsInfo` function. A local attacker could exploit this by manipulating the TAG_GPS_LAT or TAG_GPS_LONG arguments. Successful exploitation could lead to information disclosure, denial of service, or potentially arbitrary code execution.

Description OSIDB Bzimport 2026-09-14 04:51:25 UTC 
A security vulnerability has been detected in Matthias-Wandel jhead up to 3.3. This impacts the function ProcessGpsInfo of the file gpsinfo.c of the component WebP EXIF Handler. Such manipulation of the argument TAG_GPS_LAT/TAG_GPS_LONG leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report but has not responded yet.
