DESCRIPTION:
Some vulnerabilities have been reported in Apache Tomcat, which can
be exploited by malicious people to bypass certain security
restrictions and cause a DoS (Denial of Service).

1) An error within the NIO connector when transferring files using
sendfile over HTTPS can be exploited to trigger an infinite loop and
cause excessive consumption of CPU resources.

This vulnerability is reported in versions prior to 7.0.27 and
6.0.35.

2) An error within the FormAuthenticator component when handling
authentication requests can be exploited to bypass the authentication
mechanism via a specially crafted request.

This vulnerability is reported in versions prior to 7.0.29 and
6.0.35.

3) An error within the "doFilter()" method when accessing protected
resources can be exploited to bypass the CSRF prevention filter and
access the resource without a session identifier.

This vulnerability is reported in versions prior to 7.0.31 and
6.0.35.

SOLUTION:
Update to a fixed version.
