FreeBSD : FreeBSD -- named(8) DNSSEC validation Denial of Service (0f020b7b-e033-11e1-90a2-000c299b62e1)

Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Problem description :

BIND 9 stores a cache of query names that are known to be failing due
to misconfigured name servers or a broken chain of trust. Under high
query loads, when DNSSEC validation is active, it is possible for a
condition to arise in which data from this cache of failing queries
could be used before it was fully initialized, triggering an assertion
failure.
