Description Mark J. Cox (Product Security) 2003-08-26 07:32:46 EDT

CAN-2003-0688

A bug has been discovered in the handling of DNS maps in sendmail 8.12
versions before 8.12.9. A remote attacker could exploit this issue to
cause the instance of sendmail dealing with a request to crash. We believe
that the nature of the bug would make remote exploitation of this issue
difficult if at all possible.

Red Hat Linux 8.0 and 9 include versions of sendmail vulnerable to this
issue, however this issue only affects sites that have enabled the
"enhdnsbl" feature and are therefore using DNS maps.

We will have an update available soon that has a patch to correct this issue,
RHSA-2003:265
