	BIND 9.5.0a1 (Bind Forum only)

Severity: Low
Exploitable: Remotely


	When validating responses to type * (ANY) queries that return
	multiple RRsets in the answer section it is possible to trigger
	assertions checks.

	To be vulnerable you need to have enabled dnssec validation in
	named.conf by specifying trusted-keys.


	Disable / restrict recursion (to limit exposure).
	Disable DNSSEC validation (remove all trusted-keys from named.conf).


	Upgrade to BIND 9.2.8, BIND 9.3.4 or BIND 9.4.0rc2.
	Additionally this will be fixed in the upcoming BIND 9.5.0a2.


	It is recommended that anyone using DNSSEC upgrade to BIND 9.3
	as the DNSSEC implementation in BIND 9.2 has been obsoleted.

Handled on bug 163692. Don't ask me why this way and not the contrary.
