| Doc Text: |
A flaw was found in the http.client module in the Python standard library. When reading an HTTP response from a server, if no read amount is specified, the default behavior will be to use Content-Length. This issue allows a malicious server to cause the client to read large amounts of data into memory, potentially causing memory allocations errors, swapping, out-of-memory conditions or even system freezes.
