Description Vladimir Vasilev 2026-09-14 07:19:30 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A weakness has been identified in Matthias-Wandel jhead up to 3.3. This affects the function Get16u of the file exif.c of the component EXIF Parsing. This manipulation causes out-of-bounds read. The attack requires local access. The exploit has been made available to the public and could be used for attacks. The project was informed of the problem early through an issue report but has not responded yet.
