Package        : sendmail
Vulnerability  : programming error
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2006-0058
CERT advisory  : VU#834865

Mark Dowd discovered a flaw in the handling of asynchronous signals in
sendmail, a powerful, efficient, and scalable mail transport agent.
This allows a remote attacker may to exploit a race condition to
execute arbitrary code as root.

For the old stable distribution (woody) this problem has been fixed in
version 8.12.3-7.2.

For the stable distribution (sarge) this problem has been fixed in
version 8.13.4-3sarge1.

For the unstable distribution (sid) this problem has been fixed in
version 8.13.6-1.

We recommend that you upgrade your sendmail package immediately.
