Descriptions

nscd: Stack-based buffer overflow in netgroup cache

If the Name Service Cache Daemon's (nscd) fixed size cache is exhausted
by client requests then a subsequent client request for netgroup data
may result in a stack-based buffer overflow. This flaw was introduced
in glibc 2.15 when the cache was added to nscd.

This vulnerability is only present in the nscd binary.

nscd: desbordamiento de búfer en la región stack de la memoria en la caché de netgroup Si la caché de tamaño fijo del daemon de caché del servicio de nombres (nscd) se agota debido a las solicitudes de los clientes, una solicitud posterior del cliente de datos de netgroup puede provocar un desbordamiento del búfer basado en la pila. Esta falla se introdujo en glibc 2.15 cuando se agregó el caché a nscd. Esta vulnerabilidad sólo está presente en el binario nscd.

A stack-based buffer overflow flaw was found in the glibc netgroup cache. In certain conditions, its possible to trigger a stack-based buffer overflow condition that can lead to a denial of service and potentially other malicious actions that impact confidentiality and integrity.
