A vulnerability has been reported in BIND, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a deadlock error when an authoritative server processes IXFR or DDNS updates combined with a query, which can be exploited to stop the server from processing further requests.
Note: A high workload increases the chance of a deadlock.
The vulnerability is reported in versions 9.7.1 through 9.7.2-P3.
Solution: Update to version 9.7.3.
Provided and/or discovered by: The vendor credits Neustar.
