Red Hat Linux 9 Advisory: RHSA-2004:034-01 Critical: MC Buffer Overflow

red hat
Calendar Grey January 21, 2004
Dist Redhat Esm H88
An essential patch for Red Hat's mc software has been released, addressing a critical buffer overflow vulnerability that could allow remote code execution in specific symlink scenarios
This vulnerability allows remote attackers to execute arbitrary code duringsymlink conversion.

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:
