Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
To keep its cache database efficient, `named` running as a recursive resolver occasionally attempts to clean up the database. It uses several methods, including some that are asynchronous: a small chunk of memory pointing to the cache element that can be cleaned up is first allocated and then queued for later processing. It was discovered that if the resolver is continuously processing query patterns triggering this type of cache-database maintenance, `named` may not be able to handle the cleanup events in a timely manner. This in turn enables the list of queued cleanup events to grow infinitely large over time, allowing the configured `max-cache-size` limit to be significantly exceeded. This issue affects BIND 9 versions 9.16.0 through 9.16.45 and 9.16.8-S1 through 9.16.45-S1.

Se descubri\u00f3 que si el solucionador procesa continuamente patrones de consulta que desencadenan este tipo de mantenimiento de la base de datos de cach\u00e9, es posible que \\\"named\\\" no pueda manejar los eventos de limpieza de manera oportuna. Esto, a su vez, permite que la lista de eventos de limpieza en cola crezca infinitamente con el tiempo, lo que permite superar significativamente el l\u00edmite de \\\"tama\u00f1o m\u00e1ximo de cach\u00e9\\\" configurado.
