"Max Vozeler discovered that the the 'pstopnm' conversion tool did not
use the -dSAFER option when calling ghostscript. This option prohibits
file operations and calling commands within PostScript code. This flaw
could be exploited by an attacker to execute arbitrary code if he
tricked an user (or an automatic server) into processing a specially
crafted PostScript document with pstopnm.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
