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 8.0.14-1+deb8u5.

For the testing (stretch) and unstable (sid) distributions, these problems have been fixed in version 8.5.8-2.

We recommend that you upgrade your tomcat8 packages.");
