Description
It was discovered that the Kerberos client implementation in the Libraries component of OpenJDK used the sname field from the plain text part rather than encrypted part of the KDC reply message. A man-in-the-middle attacker could possibly use this flaw to impersonate Kerberos services to Java applications acting as Kerberos clients.
