## Description

DigestAuthenticator.java in the HTTP Digest Access Authentication
implementation in Apache Tomcat 5.5.x before 5.5.34, 6.x before 6.0.33, and
7.x before 7.0.12 uses Catalina as the hard-coded server secret (aka
private key), which makes it easier for remote attackers to bypass
cryptographic protection mechanisms by leveraging knowledge of this string,
a different vulnerability than CVE-2011-1184.
