Red Hat Security Advisory

Synopsis: Low: enscript security update
Advisory ID: RHSA-2005:040-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-040.html
Issue date: 2005-02-15
Updated on: 2005-02-15
Product: Red Hat Enterprise Linux
CVE Names: CAN-2004-1184 CAN-2004-1185 CAN-2004-1186
---------------------------------------------------------------------

1. Summary:

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.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Enterprise Linux Desktop version 4 - i386, x86_64
Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64

3. Problem description:

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 CAN-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 CAN-2004-1185 and CAN-2004-1186 to these issues.

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