DNS: ISC BIND Referral CNAME and DNAME Assertion Failure Denial of Service
This signature detects attempts to exploit a known vulnerability in ISC BIND9. Successful exploitation leads to denial-of-service conditions.
Extended Description

Affects BIND 9.9.9-P6, 9.9.10b1->9.9.10rc1, 9.10.4-P6, 9.10.5b1->9.10.5rc1, 9.11.0-P3, 9.11.1b1->9.11.1rc1, and 9.9.9-S8.
