CVE-2018-5736 Information

Description

An error in zone database reference counting can lead to an assertion failure if a server which is running an affected version of BIND attempts several transfers of a slave zone in quick succession. This defect could be deliberately exercised by an attacker who is permitted to cause a vulnerable server to initiate zone transfers (for example: by sending valid NOTIFY messages) causing the named process to exit after failing the assertion test. Affects BIND 9.12.0 and 9.12.1.
