Description

A vulnerability has been discovered in libapache-mod-jk, the Apache 2 connector for the Tomcat Java servlet engine.

The libapache-mod-jk connector is susceptible to information disclosure and privilege escalation because of a mishandling of URL normalization.

The nature of the fix required that libapache-mod-jk in Debian 8 'Jessie' be updated to the latest upstream release. For reference, the upstream changes associated with each release version are documented here :

http://tomcat.apache.org/connectors-doc/miscellaneous/changelog.html

For Debian 8 'Jessie', this problem has been fixed in version 1.2.46-0+deb8u1.

We recommend that you upgrade your libapache-mod-jk packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
