"The version of PGP Desktop installed on the remote host reportedly can
allow a remote, authenticated user to execute arbitrary code on the
affected host with LOCAL SYSTEM privileges.  The issue arises because
the software operates a service named 'PGPServ' or 'PGPsdkServ' that
exposes a named pipe that fails to validate the object data passed to
it.");
