Descriptions

A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it returns. The Samba DNS server itself will continue to operate, but many RPC services will not.

Se encontró un fallo en el servidor DNS de samba. Un usuario autenticado podría usar este fallo para que el servidor RPC se bloquee. Este servidor RPC, que también sirve protocolos distintos a dnsserver, será reinciado después de un breve retraso, pero es fácil para un atacante no administrativo autenticado bloquearlo nuevamente tan pronto como regrese. El servidor DNS de Samba seguirá funcionando, pero muchos servicios RPC no
