Description

What do you know—I encountered a Jetty vulnerability while trying to prepare a new 3.7.0 RC:

[ERROR] Failed to execute goal org.owasp:dependency-check-maven:5.3.0:check (default-cli) on project zookeeper: 
[ERROR] 
[ERROR] One or more dependencies were identified with vulnerabilities that have a CVSS score greater than or equal to '0.0': 
[ERROR] 
[ERROR] jetty-server-9.4.35.v20201120.jar: CVE-2020-27223
[ERROR] jetty-http-9.4.35.v20201120.jar: CVE-2020-27223

CVE-2020-27223 describes it as:

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.

This may not be the end of the world wrt. ZooKeeper, but it doesn't look good in a fresh release.
