  - CVE-2012-4431: The CSRF prevention filter could be bypassed if a request was made to a
  protected resource without a session identifier present in the request.

  - CVE-2012-2733: The checks that limited the permitted size of request headers were implemented
  too late in the request parsing process for the HTTP NIO connector. This enabled a malicious user
  to trigger an OutOfMemoryError by sending a single request with very large headers.

  - CVE-2012-4534: When using the NIO connector with sendfile and HTTPS enabled, if a client breaks
  the connection while reading the response an infinite loop is entered leading to a denial of
  service.

  - CVE-2012-3439: DIGEST authentication weakness

  - CVE-2012-3546: When using FORM authentication it was possible to bypass the security constraint
  checks in the FORM authenticator by appending /j_security_check to the end of the URL if some
  other component (such as the Single-Sign-On valve) had called request.setUserPrincipal() before
  the call to FormAuthenticator#authenticate().");
