OpenPKG Security Advisory The OpenPKG Project
http://www.openpkg.org/security.html http://www.openpkg.org
openpkg-security@openpkg.org openpkg@openpkg.org
OpenPKG-SA-2003.030 03-Jun-2003
________________________________________________________________________
Package: ghostscript
Vulnerability: execute arbitrary commands
OpenPKG Specific: no
Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= ghostscript-7.04-20021013 >= ghostscript-8.00-20021122
OpenPKG 1.2 none N.A.
OpenPKG 1.1 <= ghostscript-7.04-1.1.0 >= ghostscript-7.04-1.1.1
Dependent Packages: none
Description:
 According to a Red Hat security advisory [0], a flaw in versions of
 Ghostscript [1] before 7.07 allows malicious Postscript files to
 execute arbitrary commands even with command line option -dSAFER
 enabled. The Common Vulnerabilities and Exposures (CVE) project
 assigned the id CAN-2003-0354 [2] to the problem.
 Please check whether you are affected by running "<prefix>/bin/rpm -q
 ghostscript". If you have the "ghostscript" 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] or a mirror location,
 verify its integrity [7], build a corresponding binary RPM from it [3]
 and update your OpenPKG installation by applying the binary RPM [4].
 For the affected release OpenPKG 1.1, perform the following operations
 to permanently fix the security problem (for other releases adjust
 accordingly).
 $ ftp ftp.openpkg.org
 ftp> bin
 ftp> cd release/1.1/UPD
 ftp> get ghostscript-7.04-1.1.1.src.rpm
 ftp> bye
 $ <prefix>/bin/rpm -v --checksig ghostscript-7.04-1.1.1.src.rpm
 $ <prefix>/bin/rpm --rebuild ghostscript-7.04-1.1.1.src.rpm
 $ su -
 # <prefix>/bin/rpm -Fvh <prefix>/RPM/PKG/ghostscript-7.04-1.1.1.*.rpm
