Multiple security vulnerabilities have been fixed in the Tomcat servlet and JSP engine, which may result on bypass of security manager restrictions, information disclosure, denial of service or session fixation.
For the oldstable distribution (wheezy), these problems have been fixed in version 6.0.45+dfsg-1~deb7u1.
We recommend that you upgrade your tomcat6 packages.
