Description

It was discovered that Tomcat incorrectly performed certain security constraint checks in the FORM authenticator.

(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.
