3. Problem 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.

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.

Id Description
24037 Sendmail Signal Handler Race Condition Remote Overflow

Sendmail contains a flaw that may allow a remote attacker to gain elevated privileges. The issue is due to the sm_syslog() function which allows an attacker to pass crafted data to the setjmp(3) and longjmp(3) function causing memory corruption. This can be used to remotely execute arbitrary code without authentication.
