DESCRIPTION:
A weakness and a vulnerability 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).

(InternalNioInputBuffer.java) when parsing request headers does not
properly verify the permitted size and can be exploited to trigger an
OutOfMemoryError exception via specially crafted headers.

This vulnerability is reported in versions 6.0.0-6.0.35 and
7.0.0-7.0.27.

2) An error within DIGEST authentication mechanism does not properly
check server nonces.
