Synopsis
The remote Red Hat host is missing one or more security updates.Description
Updated sendmail packages to fix a security issue are now available for Red Hat Enterprise Linux 2.1.This update has been rated as having critical security impact by the Red Hat Security Response Team.
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 2.1, 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.
In order to correct this issue for Red Hat Enterprise Linux 2.1 users, it was necessary to upgrade the version of Sendmail from 8.11 as originally shipped to Sendmail 8.12 with the addition of the security patch supplied by Sendmail Inc. This erratum provides updated packages based on Sendmail 8.12 with a compatibility mode enabled. After updating to these packages, users should pay close attention to their sendmail logs to ensure that the upgrade completed sucessfully.
