CVE-2019-9511

Some HTTP/2 implementations are vulnerable to window size manipulation and
stream prioritization manipulation, potentially leading to a denial of service.
The attacker requests a large amount of data from a specified resource over
multiple streams. They manipulate window size and stream priority to force the
server to queue the data in 1-byte chunks. Depending on how efficiently this
data is queued, this can consume excess CPU, memory, or both.
