All other types of references use String arguments, but approximately half of the EDB references use Fixnums. Fix this by using Strings here too.

'Description' => %q{
|
|
This module exploits a buffer overflow in the Eureka Email 2.2q
|
|
client that is triggered through an excessively long ERR message.
|
|
|
|
NOTE: this exploit isn't very reliable. Unfortunately reaching the
|
|
vulnerable code can only be done when manually checking mail (Ctrl-M).
|
|
Checking at startup will not reach the code targeted here.
