Debian DSA-612-1 : a2ps - unsanitised input

critical Nessus Plugin ID 16008

Synopsis

The remote Debian host is missing a security-related update.

Description

Rudolf Polzer discovered a vulnerability in a2ps, a converter and pretty-printer for many formats to PostScript. The program did not escape shell meta characters properly which could lead to the execution of arbitrary commands as a privileged user if a2ps is installed as a printer filter.

Solution

Upgrade the a2ps package.

For the stable distribution (woody) this problem has been fixed in version 4.13b-16woody1.
