SynopsisThe remote name server is affected by Service Downgrade / Reflected DoS vulnerabilities.
DescriptionAccording to its self-reported version, the instance of ISC BIND 9 running on the remote name server is affected by performance downgrade and Reflected DoS vulnerabilities. This is due to BIND DNS not sufficiently limiting the number fetches which may be performed while processing a referral response.
An unauthenticated, remote attacker can exploit this to cause degrade the service of the recursive server or to use the affected server as a reflector in a reflection attack.
SolutionUpgrade to the ISC BIND version referenced in the vendor advisory.
