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.

The remote Ubuntu 16.04 ESM host has a package installed that is affected by a vulnerability as referenced in the USN-6113-1 advisory.

    It was discovered that Jhead did not properly handle certain crafted images while processing the Exif     markers. An attacker could possibly use this issue to crash Jhead, resulting in a denial of service.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
