9.4.0 and Alpha releases of 9.5.0
A sequence of queries can cause a recursive
nameserver to exit. While it is unlikely these will occur in normal
operation, an attack can use them to cause the affected versions to
exit. This attack is a denial of service, and does not allow an attacker
to gain control of affected systems.
Disable recursion ('recursion no;' set in named.conf) if it is not required by your configuration.
None known at this time.
Upgrade to BIND 9.4.1 or BIND 9.5.0.
