## Description

The HTTP Digest Access Authentication implementation in Apache Tomcat 5.5.x
before 5.5.36, 6.x before 6.0.36, and 7.x before 7.0.30 does not properly
check for stale nonce values in conjunction with enforcement of proper
credentials, which makes it easier for remote attackers to bypass intended
access restrictions by sniffing the network for valid requests.
