Jetdirect card Attack???

[James Edwards <jedwards () mail sdsu edu>]

Yesterday, one of the printers here in ITS began printing a Jetdirect 
Diagnostic Page showing a S/W Exception 00fb and a core dump 
("Registers", "Stack", and "Register Pointer Memory Dump" in Hex). I 
changed the slot, and the error followed (from EIO1 to EIO2), 
therefore I guessed that the card was bad. Today another printer 
began to share the same symptoms. I have a hard time believing that 
two cards would go bad at the same time

Has anyone else noted this phenomenon??

Could it be a different type of printer attack than the port 515 attacks??

(PS, I've already called John and notified him--he asked me to post 
here (I'm also posting to the Security Focus list) for feedback.)
