RHSA-2003:209: updated ghostscript packages fix vulnerabilities



Updated packages are available for GNU Ghostscript under the iSeries and pSeries architectures which fix various security vulnerabilities.

Ghostscript is a program for displaying PostScript files or printing them to non-PostScript printers. An untrusted PostScript file can cause ghostscript to execute arbitrary commands due to insufficient checking. Since ghostscript is often used during the course of printing a document (and is run as user lp), all users should install the packages contained in this erratum. The problem was fixed in the 6.53 source release of GNU Ghostscript, and the fix has been backported and applied to the packages referenced by this advisory. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2002-0363 to this issue. Please note that this vulnerability is different to the "local file read" issue corrected by our previous Ghostscript errata (RHSA-2001:112 and RHSA-2001:138) A flaw in unpatched versions of Ghostscript before 7.07 allows malicious postscript files to execute arbitrary commands even with -dSAFER enabled. Note that this vulnerability does not affect Ghostscript when the Red Hat -dPARANOIDSAFER option is used. Therefore, a malicious print job cannot be used to exploit this vulnerability under Red Hat Linux. Users of Ghostscript are advised to upgrade to these updated packages, which contain a backported patch and are not vulnerable to this issue.
