NVD Description

Note: Versions mentioned in the description apply only to the upstream jetty9 package and not the jetty9 package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

In Eclipse Jetty 9.4.6.v20170531 to 9.4.36.v20210114 (inclusive), 10.0.0, and 11.0.0 when Jetty handles a request containing multiple Accept headers with a large number of “quality” (i.e. q) parameters, the server may enter a denial of service (DoS) state due to high CPU usage processing those quality values, resulting in minutes of CPU time exhausted processing those quality values.
