[Bug 64563] New: Special payload length of websocket frame leads to high CPU usage

Bugzilla from bugzilla@apache.org
https://bz.apache.org/bugzilla/show_bug.cgi?id=64563

            Bug ID: 64563
           Summary: Special payload length of websocket frame leads to
                    high CPU usage
           Product: Tomcat 9
           Version: 9.0.21
          Hardware: PC
            Status: NEW
          Severity: major
          Priority: P2
         Component: WebSocket
          Assignee: [hidden email]
          Reporter: [hidden email]
  Target Milestone: -----

Created attachment 37336
  --> https://bz.apache.org/bugzilla/attachment.cgi?id=37336&action=edit
the debug result

If all bits(7+64) of the payload length in one websocket frame are 1,the length
will be resolved to a negative value which will cause an endless loop.The
result is CPU usage is high and will not drop!
