-----BEGIN PGP SIGNED MESSAGE----- =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2003.0390 -- RHSA-2003:181-01 Updated ghostscript packages fix vulnerability 03 June 2003 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: ghostscript Publisher: Red Hat Operating System: Red Hat Linux 9 Red Hat Linux 8.0 Red Hat Linux 7.3 Red Hat Linux 7.2 Red Hat Linux 7.1 Linux Impact: Execute Arbitrary Code/Commands Access Required: Remote CVE Names: CAN-2003-0354 - --------------------------BEGIN INCLUDED TEXT-------------------- - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated ghostscript packages fix vulnerability Advisory ID: RHSA-2003:181-01 Issue date: 2003-05-30 Updated on: 2003-05-30 Product: Red Hat Linux Keywords: Cross references: Obsoletes: CVE Names: CAN-2003-0354 - --------------------------------------------------------------------- 1. Topic: New ghostscript packages fixing a command execution vulnerability are now available. 2. Relevant releases/architectures: Red Hat Linux 7.1 - i386 Red Hat Linux 7.2 - i386, ia64 Red Hat Linux 7.3 - i386 Red Hat Linux 8.0 - i386 Red Hat Linux 9 - i386 3. Problem description: GNU Ghostscript is an interpreter for the PostScript language, and is often used when printing to printers that do not have their own built-in PostScript interpreter. 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. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. To update all RPMs for your particular architecture, run: rpm -Fvh [filenames] where [filenames] is a list of the RPMs you wish to upgrade. Only those RPMs which are currently installed will be updated. Those RPMs which are not installed but included in the list will not be updated. Note that you can also use wildcards (*.rpm) if your current directory *only* contains the desired RPMs. Please note that this update is also available via Red Hat Network. Many people find this an easier way to apply updates. To use Red Hat Network, launch the Red Hat Update Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
