ISC BIND Response Policy Zones (RPZ) DNAME / CNAME Parsing Remote DoS
High Nessus Plugin ID 55533
SynopsisThe remote name server may be affected by a denial of service vulnerability.
DescriptionAccording to its self-reported version number, the remote installation of BIND is potentially affected by a denial of service vulnerability. If an attacker sends a specially crafted request to a BIND server that has recursion enabled and Response Policy Zones (RPZ) configured, it may cause the name server process to crash.
Note that Nessus has only relied on the version itself and has not attempted to determine whether or not the install is actually affected.
SolutionUpgrade to BIND 9.8.0-P3 or later.
