More information:

Dawid Golunski from legalhackers.com discovered that Debian's version of Tomcat 6 was vulnerable to a local privilege escalation. Local attackers who have gained access to the server in the context of the tomcat6 user through a vulnerability in a web application were able to replace the file with a symlink to an arbitrary file.

For Debian 7 Wheezy, these problems have been fixed in version 6.0.45+dfsg-1~deb7u2.

We recommend that you upgrade your tomcat6 packages.
