ISC BIND 9 resolver.c Multiple DNS Cookie Packet Handling DoS
High Nessus Plugin ID 90000
SynopsisThe remote name server is affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number, ISC BIND installed on the remote name server is affected by a denial of service vulnerability in file resolver.c when DNS cookies are enabled. An unauthenticated, remote attacker can exploit his, via a malformed packet with more than one cookie option, to cause an INSIST assertion failure and daemon exit.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to ISC BIND version 9.10.3-P4 or later.
