Details

It was discovered that Tomcat incorrectly performed certain security
constraint checks in the FORM authenticator. A remote attacker could
possibly use this flaw with a specially-crafted URI to bypass security
constraint checks. This issue only affected Ubuntu 10.04 LTS, Ubuntu 11.10
and Ubuntu 12.04 LTS. (CVE-2012-3546)

It was discovered that Tomcat incorrectly handled requests that lack a
session identifier. A remote attacker could possibly use this flaw to
bypass the cross-site request forgery protection. (CVE-2012-4431)

It was discovered that Tomcat incorrectly handled sendfile and HTTPS when
the NIO connector is used. A remote attacker could use this flaw to cause
Tomcat to stop responsing, resulting in a denial of service. This issue
only affected Ubuntu 10.04 LTS, Ubuntu 11.10 and Ubuntu 12.04 LTS.
