CVE-2019-9511 Open this link in a new tabHow to fix?
Upgrade Ubuntu:18.04 nghttp2 to version 1.30.0-1ubuntu1+esm2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nghttp2 package and not the nghttp2 package as distributed by Ubuntu.
See How to fix? for Ubuntu:18.04 relevant fixed versions and status.
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.
