Upgrade to:
BIND 9 version 9.9.9-P3
BIND 9 version 9.10.4-P3
BIND 9 version 9.11.0rc3
Testing by ISC has uncovered a critical error condition which can occur when a nameserver is constructing a response. A defect in the rendering of messages into packets can cause named to exit with an assertion failure in buffer.c while constructing a response to a query that meets certain criteria.
This assertion can be triggered even if the apparent source address isn't allowed to make queries (i.e. doesn't match 'allow-query').
Who is vulnarable:
All servers are vulnerable if they can receive request packets from any source.
