Description Vincent Danen 2013-07-26 21:25:01 UTC 
It was reported that when ISC implemented support for RFC 5011 in BIND 9.7, it inadvertently introduced a bug that would cause named to crash when receiving a specially crafted query which included malformed rdata.  The named daemon would terminate with an assertion failure when rejecting the malformed query.

As this was introduced in BIND 9.7, earlier versions are unaffected by this flaw.
