Doc Text:
A denial of service flaw was found in the way BIND parsed certain malformed DNSSEC keys. A remote attacker could use this flaw to send a specially crafted DNS query (for example, a query requiring a response from a zone containing a deliberately malformed key) that would cause named functioning as a validating resolver to crash.

Description Kurt Seifried 2015-09-01 19:58:43 EDT 
The following flaw, reported by ISC, was found in all versions of BIND 9 (9.0.0 through 9.8.8, 9.9.0 through 9.9.7-P2, and 9.10.0 through 9.10.2-P3):

Parsing a malformed DNSSEC key can cause a validating resolver to exit
due to a failed assertion in buffer.c. It is possible for a remote
attacker to deliberately trigger this condition, for example by using a
query which requires a response from a zone containing a deliberately
malformed key.

ISC would like to thank Hanno Böck from the Fuzzing Project for
discovering and reporting this defect. We would also like to express
our appreciation to the developers of the American Fuzzy Lop tool, which
has been instrumental in revealing recently-disclosed vulnerabilities in
BIND.

Acknowledgements:

Red Hat would like to thank ISC for reporting this issue. Upstream acknowledges Hanno Böck as the original reporter.
