Package : a2ps Vulnerability : unsanitised input Problem-Type : local Debian-specific: no CVE ID : CAN-2004-1170 BugTraq ID : 11025 Debian Bug : 283134

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.

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

For the unstable distribution (sid) this problem has been fixed in version 4.13b-4.2.

We recommend that you upgrade your a2ps package.
