Red Hat Security Advisory
Synopsis: Updated mc packages resolve several vulnerabilities
Advisory ID: RHSA-2004:172-01
Issue date: 2004-05-19
Updated on: 2004-05-19
Product: Red Hat Enterprise Linux
Keywords: mc buffer overflow format string temporary file
Cross references:
Obsoletes:
CVE Names: CAN-2004-0226 CAN-2004-0231 CAN-2004-0232
----------------------------------------------------------------------
1. Topic:
Updated mc packages that resolve several buffer overflow vulnerabilities, one format string vulnerability and several temporary file creation vulnerabilities are now available.
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.
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.
4. 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:
https://rhn.redhat.com/help/latest-up2date.pxt
5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):
118302 - One more buffer overflow in mc's vfs code
