ISC BIND 9 Recursive Resolver Malformed Zone DoS

high Nessus Plugin ID 66838


The remote name server is prone to a denial of service attack.


According to its self-reported version number, the remote installation of BIND can be forced to crash via a 'RUNTIME_CHECK' error in 'resolver.c' caused by specially crafted queries for a record in a malformed zone to a recursive resolver.

Note that Nessus has only relied on the version itself and has not attempted to determine whether or not the install is actually affected.


Upgrade to BIND version 9.9.3-P1 / 9.8.5-P1 / 9.6-ESV-R9-P1 or later, or apply the vendor-supplied patch.
