buffer.c in named in ISC BIND 9.x before 9.9.7-P3 and 9.10.x before 9.10.2-P4 allows remote attackers to cause a denial of service (assertion failure and daemon exit) by creating a zone containing a malformed DNSSEC key and issuing a query for a name in that zone.
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.
