Sun Solaris RPC Services Library (librpcsvc) denial of service

solaris-rpc-services-dos (37194) The risk level is classified as MediumMedium Risk

Description:

Sun Solaris is vulnerable to a denial of service, caused by an error in the RPC Services Library (librpcsvc). If the automountd service is used to gain remote access to NFS servers with an overly large number of exported file systems, a local attacker could exploit this vulnerability to crash the automountd daemon.
