bind: TKEY query handling flaw leading to denial of service

named in ISC BIND 9.x before 9.9.7-P2 and 9.10.x before 9.10.2-P3 allows remote attackers to cause a denial of service (REQUIRE assertion failure and daemon exit) via TKEY queries.

Certain HP Access Controller, Fabric Module, Firewall, Router, Switch, and UTM Appliance products; certain HP 3Com Access Controller, Router, and Switch products; certain HP H3C Access Controller, Firewall, Router, Switch, and Switch and Route Processing Unit products; and certain Huawei Firewall/Gateway, Router, Switch, and Wireless products do not properly implement access control as defined in h3c-user.mib 2.0 and hh3c-user.mib 2.0, which allows remote authenticated users to discover credentials in UserInfoEntry values via an SNMP request with the read-only community.
