-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project OpenPKG-SA-2005.003 17-Jan-2005 ________________________________________________________________________ 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 Dependent Packages: none 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. 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][6], fetch it from the OpenPKG FTP service [7][8] or a mirror location, verify its integrity [9], 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> 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 ________________________________________________________________________ References: [0] [1] [2] [3] [4] [5] [6] [7] [8] [9] ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from and hkp:// Follow the instructions on for details on how to verify the integrity of this advisory. ________________________________________________________________________ -----BEGIN PGP SIGNATURE----- Comment: OpenPKG <> iD8DBQFB67F5gHWT4GPEy58RAiuUAKCaVwm6qztuFo7Gx7aZP6ZrITKjgQCfdGrL ZrkstKQlbfIuKDISsjhjYHE= =+cr1 -----END PGP SIGNATURE----- ______________________________________________________________________ The OpenPKG Project Project Announcement List
