                   Red Hat, Inc. Red Hat Security Advisory

Synopsis:          Ghostscript command execution vulnerability
Advisory ID:       RHSA-2002:083-22
Issue date:        2002-05-07
Updated on:        2002-06-03
Product:           Red Hat Linux
Keywords:          ghostscript SAFER PARANOIDSAFER
Cross references:  
Obsoletes:         RHSA-2001:112 RHSA-2001:138
CVE Names:         CAN-2002-0363
---------------------------------------------------------------------

1. Topic:

Updated packages are available for GNU Ghostscript which fix a
vulnerability found during Postscript interpretation.

2. Relevant releases/architectures:

Red Hat Linux 6.2 - alpha, i386, noarch, sparc

Red Hat Linux 7.0 - alpha, i386, noarch

Red Hat Linux 7.1 - alpha, i386, ia64

Red Hat Linux 7.2 - i386, ia64

Red Hat Linux 7.3 - i386

3. Problem description:

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 these fixed packages.

The problem is 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)

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.
