Description Andrej Nemec 2018-02-05 13:13:18 UTC
An integer underflow bug in the process_EXIF function of the exif.c file of jhead 3.00 raises a heap-based buffer over-read when processing a malicious JPEG file, which may allow a remote attacker to cause a denial-of-service attack or unspecified other impact.
