SynopsisThe remote name server is affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number, the remote installation of BIND is affected by a denial of service vulnerability due to improper parsing of incorrect class attributes in db.c. An unauthenticated, remote attacker can exploit this, via a malformed class attribute, to trigger a REQUIRE assertion failure, resulting in a denial of service condition.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to BIND version 9.9.8-P2 / 9.9.8-S3 / 9.10.3-P2 or later.
Note that 9.9.8-S3 is a preview version of BIND provided exclusively to ISC Support customers.
