    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
    
    Summary:
    
    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
    
    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 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.
