RHSA-2004:172 - Security Advisory

Topic

Updated mc packages that resolve several buffer overflow vulnerabilities,
one format string vulnerability and several temporary file creation
vulnerabilities are now available.

Description

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

Several buffer overflows, several temporary file creation vulnerabilities,
and one format string vulnerability have been discovered in Midnight
Commander. These vulnerabilities were discovered mostly by Andrew V.
Samoilov and Pavel Roskin. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the names CAN-2004-0226,
CAN-2004-0231, and CAN-2004-0232 to these issues.

Users should upgrade to these updated packages, which contain a backported
patch to correct these issues.

Solution

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
