Topic

Updated sendmail packages to fix a security issue are now available for Red
Hat Enterprise Linux 3 and 4.

This update has been rated as having critical security impact by the Red
Hat Security Response Team.

Description

Sendmail is a Mail Transport Agent (MTA) used to send mail between machines.

A flaw in the handling of asynchronous signals was discovered in Sendmail.
A remote attacker may be able to exploit a race condition to execute
arbitrary code as root. The Common Vulnerabilities and Exposures project
assigned the name CVE-2006-0058 to this issue.

By default on Red Hat Enterprise Linux 3 and 4, Sendmail is configured to
only accept connections from the local host. Therefore, only users who have
configured Sendmail to listen to remote hosts would be able to be remotely
exploited by this vulnerability.

Users of Sendmail are advised to upgrade to these erratum packages, which
contain a backported patch from the Sendmail team to correct this issue.

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.
