[New-bugs-announce] [issue20777] PyArg_ParseTupleAndKeywords does not respect arguments format.

[Carlos Ferreira]

New submission from Carlos Ferreira:

PyArg_ParseTupleAndKeywords is not respecting the format string "sy*ss"

When using the format "sbss" with the following valid arguments
"enp0s8", 0, "08:00:27:da:b3:47", "08:00:27:11:22:33"
there is no error and the function succeeds in parsing the arguments.

But when passing the following valid arguments,
"8bf2f93c-8f44-4960-a2de-71f87130882e", bytes(list([0,0,0,1])), "08:00:27:11:22:33", "10.0.0.3"
it will fail stating that the 3rd argument has a null character.
