Ubuntu Security Notice USN-3081-1
September 19, 2016

tomcat6, tomcat7, tomcat8 vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS


The system could be made to run programs as an administrator.

Software Description:
- tomcat8: Servlet and JSP engine
- tomcat7: Servlet and JSP engine
- tomcat6: Servlet and JSP engine


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 LTS:
  libtomcat8-java                 8.0.32-1ubuntu1.2
  tomcat8                         8.0.32-1ubuntu1.2

Ubuntu 14.04 LTS:
  libtomcat7-java                 7.0.52-1ubuntu0.7
  tomcat7                         7.0.52-1ubuntu0.7

Ubuntu 12.04 LTS:
  libtomcat6-java                 6.0.35-1ubuntu3.8
  tomcat6                         6.0.35-1ubuntu3.8

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