Advisory ID: RHSA-2004:464-02
Advisory URL: https://rhn.redhat.com/errata/RHSA-2004-464.html
Issue date: 2005-01-05
Updated on: 2005-01-05

----------------------------------------------------------------------

1. Summary:

An updated mc package that resolves several shell escape security issues is now available.

[Updated 5 January 2005]
Packages have been updated to include the gmc and mcserv packages which were left out of the initial errata.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux WS version 2.1 - i386

3. Problem description:

Midnight Commander (mc) is a visual shell much like a file manager.

Shell escape bugs have been discovered in several of the mc vfs backend scripts. An attacker who is able to influence a victim to open a specially-crafted URI using mc could execute arbitrary commands as the victim. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0494 to this issue.

Users of mc should upgrade to this updated package which contains backported patches and is not vulnerable to this issue.

4. Solution:
