tomcat4 - source code disclosure

A security vulnerability has been found in all Tomcat 4.x releases.
This problem allows an attacker to use a specially crafted URL to
return the unprocessed source code of a JSP page, or, under special
circumstances, a static resource which would otherwise have been
protected by security constraints, without the need for being properly
authenticated.

This problem has been fixed in version 4.0.3-3woody1 for the current
stable distribution (woody) and in version 4.1.12-1 for the unstable
release (sid). The old stable release (potato) does not contain
tomcat packages. Also, packages for tomcat3 are not vulnerable to
this problem.

We recommend that you upgrade your tomcat package immediately.
