[3.14] gh-119452: Fix a potential virtual memory allocation denial of service in http.server #142216

serhiy-storchaka · 2025-12-03T11:14:44Z

The CGI server on Windows could consume the amount of memory specified in the Content-Length header of the request even if the client does not send such much data. Now it reads the POST request body by chunks, therefore the memory consumption is proportional to the amount of sent data.

I managed to keep the test while getting rid from an explicit select(). Tested on Linux without fork(), will see how it works on Windows.
