    tomcat6 vulnerabilities
    ==========================================================================
    
    A security issue affects these releases of Ubuntu and its derivatives:
    
    - Ubuntu 12.04 LTS
    - Ubuntu 11.10
    - Ubuntu 10.04 LTS
    
    Summary:
    
    Several security issues were fixed in Apache Tomcat.
    
    Software Description:
    - tomcat6: Servlet and JSP engine
    
    Details:
    
    It was discovered that the Apache Tomcat HTTP NIO connector incorrectly
    handled header data. A remote attacker could cause a denial of service by
    sending requests with a large amount of header data. (CVE-2012-2733)
    
    It was discovered that Apache Tomcat incorrectly handled DIGEST
    authentication. A remote attacker could possibly use these flaws to perform
    a replay attack and bypass authentication. (CVE-2012-5885, CVE-2012-5886,
    CVE-2012-5887)
    
    Update instructions:
    
    The problem can be corrected by updating your system to the following
    package versions:
    
    Ubuntu 12.04 LTS:
      libtomcat6-java                 6.0.35-1ubuntu3.1
    
    Ubuntu 11.10:
      libtomcat6-java                 6.0.32-5ubuntu1.3
    
    Ubuntu 10.04 LTS:
      libtomcat6-java                 6.0.24-2ubuntu1.11
    
    In general, a standard system update will make all the necessary changes.
