Sun Solaris NFS Remote Procedure Calls (RPC) zones denial of service
| solaris-nfs-rpc-dos (44696) |  Medium Risk |
Description:
Sun Solaris is vulnerable to a denial of service, caused by an error in the NFS Remote Procedure Calls (RPC) zones implementation. A local attacker with admin privileges in a non-global zone could exploit this vulnerability to intercept and corrupt NFS traffic intended for other non-global zones, resulting in a denial of service.
