The remote Red Hat host is missing one or more security updates.
Updated Sendmail packages are available to fix a vulnerability that
may allow remote attackers to gain root privileges by sending a
carefully crafted message.
[Updated March 18 2003] Added packages for Red Hat Enterprise Linux ES
and Red Hat Enterprise Linux WS.
Sendmail is a widely used Mail Transport Agent (MTA) which is included
in all Red Hat Enterprise Linux distributions.
During a code audit of Sendmail by ISS, a critical vulnerability was
uncovered that affects unpatched versions of Sendmail prior to version
8.12.8. A remote attacker can send a carefully crafted email message
which, when processed by sendmail, causes arbitrary code to be
executed as root.
We are advised that a proof-of-concept exploit is known to exist, but
is not believed to be in the wild.
Since this is a message-based vulnerability, MTAs other than Sendmail
may pass on the carefully crafted message. This means that unpatched
versions of Sendmail inside a network could still be at risk even if
they do not accept external connections directly.
All users are advised to update to these erratum packages which
contain a backported patch to correct this vulnerability.
Red Hat would like to thank Eric Allman for his assistance with this
