Segfaults & bus errors on large commands #232

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
For the segfaults, seems like buffer overflow overwriting return pointer of 
pn53x_usb_bulk_write()

python -c 'print "06"+"00"*248'|pn53x-tamashell
=> ok

python -c 'print "06"+"00"*250'|pn53x-tamashell
=> segfault

python -c 'print "06"+"00"*252'|pn53x-tamashell
=> segfault

python -c 'print "06"+"00"*254'|pn53x-tamashell
=> Bus error
