The remote DNS server may be affected by a Denial of Service (DoS) attack vector.


Versions of ISC BIND 9.x prior to 9.9.7-P2, 9.9.9-S3, 9.10.2-P3, and 9.10.3 are unpatched for a flaw that is triggered when handling TKEY queries. With a specially crafted request, a remote attacker can cause the named service to terminate.
