========================================================================== Ubuntu Security Notice USN-1359-1 February 13, 2012
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 if it received specially crafted network traffic.
Software Description: - tomcat6: Servlet and JSP engine
Details:
It was discovered that Tomcat incorrectly performed certain caching and recycling operations. A remote attacker could use this flaw to obtain read access to IP address and HTTP header information in certain cases. This issue only applied to Ubuntu 11.10. (CVE-2011-3375)
It was discovered that Tomcat computed hash values for form parameters without restricting the ability to trigger hash collisions predictably. A remote attacker could cause a denial of service by sending many crafted parameters. (CVE-2011-4858)
It was discovered that Tomcat incorrectly handled parameters. A remote attacker could cause a denial of service by sending requests with a large number of parameters and values. (CVE-2012-0022)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: libtomcat6-java 6.0.32-5ubuntu1.2
Ubuntu 11.04: libtomcat6-java 6.0.28-10ubuntu2.3
Ubuntu 10.10: libtomcat6-java 6.0.28-2ubuntu1.6
Ubuntu 10.04 LTS: libtomcat6-java 6.0.24-2ubuntu1.10
In general, a standard system update will make all the necessary changes.
