"An updated enscript package that fixes several security issues is now
available for Red Hat Enterprise Linux 4.

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

GNU enscript converts ASCII files to PostScript.

Enscript has the ability to interpret special escape sequences. A flaw
was found in the handling of the epsf command used to insert inline
EPS files into a document. An attacker could create a carefully
crafted ASCII file which made use of the epsf pipe command in such a
way that it could execute arbitrary commands if the file was opened
with enscript by a victim. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2004-1184 to this
issue.

Additional flaws in Enscript were also discovered which can only be
triggered by executing enscript with carefully crafted command line
arguments. These flaws therefore only have a security impact if
enscript is executed by other programs and passed untrusted data from
remote users. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the names CVE-2004-1185 and CVE-2004-1186
to these issues.

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