[New-bugs-announce] [issue15977] Memory leak in _ssl.c

New submission from Daniel Sommermann:

I noticed that the function _set_npn_protocols() has the following line:

self->npn_protocols = PyMem_Malloc(protos.len);

There is no check to see if self->npn_protocols is already allocated. Thus, multiple calls to _set_npn_protocols() will leak memory. There should be a check to see if it is non-null and free the memory pointed to by self->npn_protocols before the malloc unless I am missing something.
