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.
