Details

Dawid Golunski discovered that the Tomcat init script incorrectly handled
creating log files. A remote attacker could possibly use this issue to
obtain root privileges. (CVE-2016-1240)

This update also reverts a change in behaviour introduced in USN-3024-1 by
setting mapperContextRootRedirectEnabled to True by default.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04
Ubuntu 14.04
Ubuntu 12.04

In general, a standard system update will make all the necessary changes.
