Detailed vulnerability description
The vulnerability allows a remote authenticated attacker to cause DoS condition on the target system.
The weakness exists due to an error in zone database reference counting. A remote authenticated attacker who is able to cause the target server to initiate zone transfers (e.g., can send NOTIFY messages) can cause several transfers of a slave zone in quick succession to trigger an assertion in 'rbtdb.c' and cause 'named' to crash.
