Exploit availability: No

Description

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to improper sequencing cleanup operations on upstream recursion fetch contexts. A remote attacker can trigger use-after-free error that may lead to assertion failure and cause the BIND name server (named) process to crash.

Successful exploitation of the vulnerability results in denial of service.

Mitigation
