APP: ISC BIND lwresd Query Name Denial of Service


This signature detects attempts to exploit a known vulnerability against ISC BIND's lwresd daemon. Successful exploitation could lead to denial-of-service conditions.

Extended Description

ISC BIND 9.x before 9.9.9-P2, 9.10.x before 9.10.4-P2, and 9.11.x before 9.11.0b2, when lwresd or the named lwres option is enabled, allows remote attackers to cause a denial of service (daemon crash) via a long request that uses the lightweight resolver protocol.
