This update also addresses two regressions which were introduced by the fixes for CVE-2016-5018 (when running Jasper with SecurityManager enabled) and CVE-2016-6797.

For Debian 7 Wheezy, these problems have been fixed in version 6.0.45+dfsg-1~deb7u4.

We recommend that you upgrade your tomcat6 packages.
