Subject Name:            a2ps
Subject Summary:         Any to Postscript Conversion Tool
Subject Home:            http://www.inf.enst.fr/~demaille/a2ps/
Subject Versions:        * <= 4.13b

Vulnerability Id:        CVE-2004-1170
Vulnerability Scope:     global (not OpenPKG specific)

Attack Feasibility:      run-time
Attack Vector:           local system
Attack Impact:           arbitrary code execution

Description:
    Rudolf Polzer discovered [0] a vulnerability in GNU a2ps [1], a
    converter and pretty-printer for many formats to PostScript. The
    program does 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. a2ps allows remote attackers to
    execute arbitrary commands via shell metacharacters in the filename.
