Description

Issue Overview:

An error in the parsing of incoming responses allows some records with an incorrect class to be be accepted by BIND instead of being rejected as malformed. This can trigger a REQUIRE assertion failure when those records are subsequently cached. Intentional exploitation of this condition is possible and could be used as a denial-of-service vector against servers performing recursive queries. (CVE-2015-8000 __)

CVE-2015-8461 __ was also issued today for bind, but the Amazon Linux AMI's version of bind is not impacted by that CVE.
