As part of this update, several regressions stemming from incomplete fixes for previous vulnerabilities were also fixed.

For the stable distribution (jessie), these problems have been fixed in version 7.0.56-3+deb8u6.

For the testing (stretch) and unstable (sid) distributions, these problems have been fixed in version 7.0.72-3.

We recommend that you upgrade your tomcat7 packages.");
