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 Linux 9 - 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 resolve 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 HatUpdate Agent with the following command: up2date This will start an interactive process that will result in the appropriate RPMs being upgraded on your system. 5.
