========================================================================== Ubuntu Security Notice USN-1252-1 November 08, 2011
tomcat6 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS
Summary:
Tomcat could be made to crash or expose sensitive information over the network.
Software Description: - tomcat6: Servlet and JSP engine
Details:
It was discovered that Tomcat incorrectly implemented HTTP DIGEST authentication. An attacker could use this flaw to perform a variety of authentication attacks. (CVE-2011-1184)
Polina Genova discovered that Tomcat incorrectly created log entries with passwords when encountering errors during JMX user creation. A local attacker could possibly use this flaw to obtain sensitive information. This issue only affected Ubuntu 10.04 LTS, 10.10 and 11.04. (CVE-2011-2204)
It was discovered that Tomcat incorrectly validated certain request attributes when sendfile is enabled. A local attacker could bypass intended restrictions, or cause the JVM to crash, resulting in a denial of service. (CVE-2011-2526)
It was discovered that Tomcat incorrectly handled certain AJP requests. A remote attacker could use this flaw to spoof requests, bypass authentication, and obtain sensitive information. This issue only affected Ubuntu 10.04 LTS, 10.10 and 11.04. (CVE-2011-3190)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: libtomcat6-java 6.0.32-5ubuntu1.1
Ubuntu 11.04: libtomcat6-java 6.0.28-10ubuntu2.2
Ubuntu 10.10: libtomcat6-java 6.0.28-2ubuntu1.5
Ubuntu 10.04 LTS: libtomcat6-java 6.0.24-2ubuntu1.9
