sendmail - char-to-int conversion

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 8.12.3-6.3.

For the old stable distribution (potato) this problem has been
fixed in version 8.9.3-26.

For the unstable distribution (sid) this problem has been
fixed in version 8.12.9-1.

We recommend that you upgrade your sendmail packages.
