SynopsisThe remote name server is affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number, the instance of ISC BIND running on the remote name server is 9.x.x prior to 9.9.13-P1, 9.10.x prior to 9.10.8-P1, 9.11.x prior to 9.11.4-P1, or 9.12.x prior to 9.12.2-P1. It is, therefore, affected by a denial of service vulnerability in the deny-answer-aliases feature.
