McAfee Firewall Enterprise ISC BIND Record Handling Lockup Vulnerability
Versions 8.2.x prior to 8.2.1P06, and 8.3.x prior to 8.3.0P02
The vulnerability is caused due to an error when handling queries for certain records and can be exploited to cause the named process to lockup.
If specific combinations of RDATA are loaded into a nameserver, either via cache or an authoritative zone, a subsequent query for a related record will cause named to lock up.
Update to version 8.2.1P06 or 8.3.0P02 when available
