Descriptions

Resolver caches and authoritative zone databases that hold significant numbers of RRs for the same hostname (of any RTYPE) can suffer from degraded performance as content is being added or updated, and also when handling client queries for this name.
This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.4-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.27-S1.

Las cachés de resolución y las bases de datos de zonas autorizadas que contienen cantidades significativas de RR para el mismo nombre de host (de cualquier RTYPE) pueden sufrir un rendimiento degradado a medida que se agrega o actualiza contenido, y también al manejar consultas de clientes para este nombre. Este problema afecta a las versiones de BIND 9, 9.11.0 a 9.11.37, 9.16.0 a 9.16.50, 9.18.0 a 9.18.27, 9.19.0 a 9.19.24, 9.11.4-S1 a 9.11.37-S1. 9.16.8-S1 a 9.16.50-S1 y 9.18.11-S1 a 9.18.27-S1.

A flaw was found in the bind9 package, where a hostname with significant resource records may slow down bind's resolver cache and authoritative zone databases while these records are being added or updated. In addition, client queries for the related hostname may cause the same issue. This vulnerability may lead to a denial of service.
