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.
