Descriptions

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.

Un error en el conteo de la base de datos de la zona puede conducir a un fallo de aserción si un servidor que está ejecutando una versión afectada de BIND intenta realizar varias transferencias hacia una zona esclava en rápida sucesión. Este defecto podría ser aprovechado deliberadamente por un atacante al que se le permite hacer que un servidor vulnerable inicie transferencias de zona (por ejemplo, mediante el envío de mensajes NOTIFY válidos), lo que provoca que el proceso named se cierre tras fallar la prueba de aserción. Afecta a BIND en versiones 9.12.0 y 9.12.1.
