PARTIAL Summary
Integer overflow in the InitialDirContext in Java Runtime Environment (JRE) 1.4.2, 1.5.0 and possibly other versions allows remote attackers to cause a denial of service (Java exception and failed DNS requests) via a large number of DNS requests, which causes the xid variable to wrap around and become negative.
