This signature detects attempts to exploit a known vulnerability against ISC BIND. Attackers can send crafted malicious data to cause denial of service condition to the target service.
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.
