+ <p>The fix for bug <a

introduced a memory leak. The object
+ introduced to collect metrics for HTTP upgrade connections was not

+ closed. This created a memory leak that, over time, could lead to a
+ denial of service via an OutOfMemoryError.</p>
+
+ <p>This was fixed with commit

href="https://github.com/apache/tomcat/commit/d27535bdee95d252418201eb21e9d29476aa6b6a";>d27535bd</a>.</p>
+
+ <p>The memory leak was reported publicly via the users mailing list on 23
+ September 2021. The security implications were identified by the Tomcat
