If OCSP checks are used, this could result in client certificates that should have been rejected to be accepted.

For the oldstable distribution (jessie), this problem has been fixed in version 1.1.32~repack-2+deb8u1.

For the stable distribution (stretch), this problem has been fixed in version 1.2.12-2+deb9u1.

We recommend that you upgrade your tomcat-native packages.

For the detailed security status of tomcat-native please refer to its security tracker page at: [link moved to references]");
