A security issue affects these releases of Ubuntu and its derivatives:
Evince could be made to crash or run programs as your login if it opened a specially crafted file.
It was discovered that Evince did not properly parse AFM font files when processing DVI files. If a user were tricked into opening a specially crafted DVI file, an attacker could cause Evince to crash or potentially execute arbitrary code with the privileges of the user invoking the program.

The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
