Thanks Alexander Buchkovsky for the fix: it has been merged into 3.6, 3.7 and master branches. Thanks Oleksandr Buchkovskyi for the bug report!


I looked at the Python 2.7 code and it doesn't look to be impacted by this bug.

Modules/_multiprocessing/pipe_connection.c uses ReadFile() and PeekNamedPipe(), but the result type of the two C functions using it is not a PyObject* and conn_recv_string() looks good to me. Moreover, the type of the buflength parameter of conn_recv_string() is size_t, so there is no signed issue.
