gh-119451: Fix a potential denial of service in http.client (GH-119454)
|
||||||
|
|
||||||
|
Reading the whole body of the HTTP response could cause OOM if
|
||||||
|
the Content-Length value is too large even if the server does not send
|
||||||
|
a large amount of data. Now the HTTP client reads large data by chunks,
|
||||||
|
therefore the amount of consumed memory is proportional to the amount
|
||||||
|
of sent data.
|
||||||
|
