Package        : tomcat4
Vulnerability  : source disclosure
Problem-Type   : remote
Debian-specific: no
CVE Id         : CAN-2002-1394

A security vulnerability has been confirmed to exist in Apache Tomcat
4.0.x releases, which allows to use a specially crafted URL to return
the unprocessed source of a JSP page, or, under special circumstances,
a static resource which would otherwise have been protected by a
security constraint, without the need for being properly
authenticated.  This is based on a variant of the exploit that was
identified as CAN-2002-1148.

For the current stable distribution (woody) this problem has been
fixed in version 4.0.3-3woody2.

The old stable distribution (potato) does not contain tomcat packages.

For the unstable distribution (sid) this problem does not exist in the
current version 4.1.16-1.

We recommend that you upgrade your tomcat packages.
