"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).

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."
