=====================================================================

1. Summary:

An updated enscript packages that fixes several security issues is now
available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64

3. Description:

GNU enscript converts ASCII files to PostScript(R) language files and
spools the generated output to a specified printer or saves it to a file.
Enscript can be extended to handle different output media and includes
options for customizing printouts.

Two buffer overflow flaws were found in GNU enscript. An attacker could
craft an ASCII file in such a way that it could execute arbitrary commands
if the file was opened with enscript with the "special escapes" option (-e
or --escapes) enabled. (CVE-2008-3863, CVE-2008-4306)

All users of enscript should upgrade to these updated packages, which
contain backported patches to correct these issues.
