Package        : tomcat4
Vulnerability  : incorrect input handling
Problem-Type   : remote
Debian-specific: no

Aldrin Martoq has discovered a denial of service (DoS) vulnerability in
Apache Tomcat 4.0.x. Sending several non-HTTP requests to Tomcat's HTTP
connector makes Tomcat reject further requests on this port until it is
restarted.

For the current stable distribution (woody) this problem has been fixed
in version 4.0.3-3woody3.

For the unstable distribution (sid) this problem does not exist in the
current version 4.1.24-2.

We recommend that you upgrade your tomcat4 packages and restart the
tomcat server.
