This signature detects attempts to exploit a known vulnerability against ISC BIND. A successful attack can result in a denial-of-service condition.
resolver.c in named in ISC BIND 9.10.x before 9.10.3-P4, when DNS cookies are enabled, allows remote attackers to cause a denial of service (INSIST assertion failure and daemon exit) via a malformed packet with more than one cookie option.
