DNS: ISC BIND Delegation Handling Resource Exhaustion Remote Denial of Service


This signature detects attempts to exploit a known vulnerability against ISC Bind. A successful attack can result in a denial-of-service condition.

Extended Description

ISC BIND 9.0.x through 9.8.x, 9.9.0 through 9.9.6, and 9.10.0 through 9.10.1 does not limit delegation chaining, which allows remote attackers to cause a denial of service (memory consumption and named crash) via a large or infinite number of referrals.
