Security Advisory: Moderate
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Updated mc packages that fix several security issues are now available for
Red Hat Enterprise Linux 2.1.
This update has been rated as having moderate security impact by the Red Hat
Security Response Team.
Midnight Commander is a visual shell much like a file manager.
Several denial of service bugs were found in Midnight Commander. These bugs
could cause Midnight Commander to hang or crash if a victim opens a
carefully crafted file. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the names CAN-2004-1009, CAN-2004-1090,
CAN-2004-1091, CAN-2004-1093 and CAN-2004-1174 to these issues.
A filename quoting bug was found in Midnight Commander's FISH protocol
handler. If a victim connects via embedded SSH support to a host containing
a carefully crafted filename, arbitrary code may be executed as the user
running Midnight Commander. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2004-1175 to this issue.
A buffer overflow bug was found in the way Midnight Commander handles
directory completion. If a victim uses completion on a maliciously crafted
directory path, it is possible for arbitrary code to be executed as the
user running Midnight Commander. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CAN-2005-0763 to this issue.
Users of mc are advised to upgrade to these packages, which contain
backported security patches to correct these issues.
