Debian 3.0 DSA-278-1 Critical: Sendmail Buffer Overflow Exploit

Michal Zalewski discovered a buffer overflow, triggered by a char to
int conversion, in the address parsing code in sendmail, a widely used
powerful, efficient, and scalable mail transport agent. This problem
is potentially remotely exploitable.

For the stable distribution (woody) this problem has been
fixed in version 8.12.3-6.2.
