Description

The vulnerability allows a remote unauthenticated user to cause DoS conditions on the target system.
The weakness is due to imptoper input validation. By returning a recursive response containing a specially crafted DNAME answer, a remote attacker can trigger a flaw in 'db.c' or 'resolver.c' and cause the target resolver to crash.
Successful exploitation of the vulnerability results in denial of service on the vulnerable system.

Remediation

Update to version 9.9.9-P4, 9.10.4-P4, 9.11.0-P1.
