Description Mark J. Cox 2003-09-17 09:47:53 UTC

There is a bug in the prescan() function of Sendmail versions prior to and
including 8.12.9. The sucessful exploitation of this bug can lead to heap
and stack structure overflows. Although no exploit currently exists, this
issue is locally exploitable and may also be remotely exploitable.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2003-0694 to this issue.

Michal Zalewski notified us of this issue Sep16 due to be public Sep23, although
it may have leaked http://hedera.linuxnews.pl/_news/2003/09/17/_long/2170.html
