Ubuntu 10.04 LTS / 10.10 / 11.04 / 11.10 : tomcat6 vulnerabilities (USN-1359-1)

Medium Nessus Plugin ID 57933


The remote Ubuntu host is missing a security-related patch.


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.

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).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libtomcat6-java package.
