3. Problem description:

Fetchmail is a remote mail retrieval and forwarding utility.

A buffer overflow was discovered in fetchmail's POP3 client.  A malicious
server could cause send a carefully crafted message UID and cause fetchmail
to crash or potentially execute arbitrary code as the user running
fetchmail.  The Common Vulnerabilities and Exposures project assigned the
name CAN-2005-2335 to this issue.

Users of fetchmail should update to this erratum package which contains a
backported patch to correct this issue.

4. Solution:

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

This update is available via Red Hat Network.  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.
