Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/sendmail-8.13.7-i486-1_slack10.2.tgz:
Upgraded to sendmail-8.13.7.
Fixes a potential denial of service problem caused by excessive recursion
leading to stack exhaustion when attempting delivery of a malformed MIME
message. This crashes sendmail's queue processing daemon, which in turn
can lead to two problems: depending on the settings, these crashed
processes may create coredumps which could fill a drive partition; and
such a malformed message in the queue will cause queue processing to
cease when the message is reached, causing messages that are later in
the queue to not be processed.
