mc security update

Synopsis

mc security update

Type/Severity

Security Advisory: Low

Topic

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.

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.
