Red Hat: RHSA-2002:294-10 Critical: OpenSSL Certificate Validation Flaw

red hat
Calendar Grey December 17, 2002
Dist Redhat Esm H88
The latest Fetchmail updates have rectified a critical vulnerability allowing remote code execution on Red Hat Linux iterations before 6.2.0.
This bug allows a remote attacker to crash Fetchmail and potentially execute arbitrary code by sending a carefully crafted email which is then parsed by Fetchmail.

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.
