In Eclipse Jetty version 9.3.x and 9.4.x, the server is vulnerable to Denial of Service conditions if a remote client sends either large SETTINGs frames container containing many settings, or many small SETTINGs frames. The vulnerability is due to the additional CPU and memory allocations required to handle changed settings
Created jetty tracking bugs for this issue:
Affects: fedora-all [bug 1696088]
Can you provide reproducer and/or reference to upstream fix? I've checked upstream Bugzilla, Github issue tracker and git commit logs, but I can't find anything that relates to this vulnerability.
