Descriptions

Processing of repeated responses to the same query, where both responses contain ECS pseudo-options, but where the first is broken in some way, can cause BIND to exit with an assertion failure.

'Broken' in this context is anything that would cause the resolver to reject the query response, such as a mismatch between query and answer name.
This issue affects BIND 9 versions 9.11.4-S1 through 9.11.37-S1 and 9.16.8-S1 through 9.16.36-S1.

El procesamiento de respuestas repetidas a la misma consulta, donde ambas respuestas contienen pseudoopciones de ECS, pero donde la primera está rota de alguna manera, puede hacer que BIND salga con un error de aserción. "Roto" en este contexto es cualquier cosa que pueda causar que el solucionador rechace la respuesta a la consulta, como una falta de coincidencia entre el nombre de la consulta y la respuesta. Este problema afecta a las versiones 9.11.4-S1 a 9.11.37-S1 y 9.16.8-S1 a 9.16.36-S1 de BIND 9.
