-- Vulnerability Details:
This vulnerability allows remote attackers to leak authentication
details on vulnerable installations of the Oracle Java Runtime. User
interaction is required to exploit this vulnerability in that the target

requested generated in the context of the Java Runtime. The Java Virtual
Machine will ignore browser policies and respond to WWW-Authenticate
requests from the Internet zone resulting in the leakage of NTLM
authentication hashes to attackers.
