evince vulnerability
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Evince could be made run programs as your login if it opened a
specially crafted file.

Software Description:
- evince: Document viewer

Details:

Felix Wilhelm discovered that Evince did not safely invoke tar when
handling tar comic book (cbt) files. An attacker could use this to
construct a malicious cbt comic book format file that, when opened
in Evince, executes arbitrary code. Please note that this update
disables support for cbt files in Evince.
