Description

This module exploits a command injection vulnerability in Evince
before version 3.24.1 when opening comic book `.cbt` files.

Some file manager software, such as Nautilus and Atril, may allow
automatic exploitation without user interaction due to thumbnailer
preview functionality.

Note that limited space is available for the payload ( Reverse Bash and Reverse Netcat payloads should be sufficiently small.

This module has been tested successfully on evince versions:

3.4.0-3.1 + nautilus 3.4.2-1+build1 on Kali 1.0.6;
3.18.2-1ubuntu4.3 + atril 1.12.2-1ubuntu0.3 on Ubuntu 16.04.
