Here are the details from the Slackware 10.2 ChangeLog:
+--------------------------+
patches/packages/sendmail-8.13.6-i486-1.tgz:  Upgraded to sendmail-8.13.6.
  This new version of sendmail contains a fix for a security problem
  discovered by Mark Dowd of ISS X-Force.  From sendmail's advisory:
    Sendmail was notified by security researchers at ISS that, under some
    specific timing conditions, this vulnerability may permit a specifically
    crafted attack to take over the sendmail MTA process, allowing remote
    attackers to execute commands and run arbitrary programs on the system
    running the MTA, affecting email delivery, or tampering with other
    programs and data on this system.  Sendmail is not aware of any public
    exploit code for this vulnerability.  This connection-oriented
    vulnerability does not occur in the normal course of sending and
    receiving email.  It is only triggered when specific conditions are
    created through SMTP connection layer commands.
