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.
