'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.
