+Package: a2ps
+Vulnerability: arbitrary code execution
+OpenPKG Specific: no

+Affected Releases: Affected Packages: Corrected Packages:
+OpenPKG CURRENT <= a2ps-4.13b-20040818 >= a2ps-4.13b-20050117
+OpenPKG 2.2 <= a2ps-4.13b-2.2.0 >= a2ps-4.13b-2.2.1
+OpenPKG 2.1 <= a2ps-4.13b-2.1.0 >= a2ps-4.13b-2.1.1

+
+Description:
+ Rudolf Polzer [0] discovered a vulnerability in 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. The Common Vulnerabilities and
+ Exposures (CVE) project assigned the identifier CAN-2004-1170 [2] to
+ the problem.
+
+ Please check whether you are affected by running "<prefix>/bin/openpkg
+ rpm -q a2ps". If you have the "a2ps" package installed and its version
+ is affected (see above), we recommend that you immediately upgrade it
+ (see Solution) [3][4].
+
+Solution:
+ Select the updated source RPM appropriate for your OpenPKG release
+ [5], fetch it from the OpenPKG FTP service [6][7] or a mirror
+ location, verify its integrity [8], build a corresponding binary RPM
+ from it [3] and update your OpenPKG installation by applying the
+ binary RPM [4]. For the most recent release OpenPKG 2.2, perform the
+ following operations to permanently fix the security problem (for
+ other releases adjust accordingly).
+
+ $ ftp ftp.openpkg.org
+ ftp> bin
+ ftp> cd release/2.2/UPD
+ ftp> get a2ps-4.13b-2.2.1.src.rpm
+ ftp> bye
+ $ <prefix>/bin/openpkg rpm -v --checksig a2ps-4.13b-2.2.1.src.rpm
+ $ <prefix>/bin/openpkg rpm --rebuild a2ps-4.13b-2.2.1.src.rpm
+ $ su -
+ # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/a2ps-4.13b-2.2.1.*.rpm
