"It was discovered that Tomcat incorrectly handled certain requests
submitted using chunked transfer encoding. A remote attacker could use
this flaw to cause the Tomcat server to stop responding, resulting in
a denial of service. This issue only affected Ubuntu 10.04 LTS and
Ubuntu 12.04 LTS. (CVE-2012-3544)

It was discovered that Tomcat incorrectly handled certain
authentication requests. A remote attacker could possibly use this
flaw to inject a request that would get executed with a victim's
credentials. This issue only affected Ubuntu 10.04 LTS, Ubuntu 12.04
LTS, and Ubuntu 12.10. (CVE-2013-2067)

It was discovered that Tomcat sometimes exposed elements of a previous
request to the current request. This could allow a remote attacker to
possibly obtain sensitive information. This issue only affected Ubuntu
12.10 and Ubuntu 13.04. (CVE-2013-2071).

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."
