SynopsisThe remote host is missing a vendor-supplied security patch
DescriptionThe remote host is missing the patch for the advisory SUSE-SA:2006:017 (sendmail).
The popular MTA sendmail is vulnerable to a race condition when handling signals.
Under certain circumstances this bug can be exploited by an attacker to execute commands remotely.
Sendmail was the default MTA in SuSE Linux Enterprise Server 8. Later products use postfix as MTA.
Thanks to Mark Dowd who found this bug.
