Artifex MuJS CVE-2018-6191 Integer Overflow Vulnerability

Artifex MuJS is prone to an integer-overflow because it fails to adequately bounds-check user-supplied data before copying it into an insufficiently sized buffer.

An attacker can exploit this issue to cause denial-of-service condition. Due to the nature of this issue, arbitrary code execution may be possible but this has not been confirmed.

Artifex MuJS version 1.0.2 and prior versions are vulnerable.
