calculate the length of strings. If a user were tricked into scanning
for printers, a remote attacker could send a specially crafted packet
and possibly execute arbitrary code.

Elias Pipping discovered that temporary files were not handled safely
in certain situations when converting PDF to PS. A local attacker
could cause a denial of service.

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
