+ <cve>CVE-2020-11996</cve></p>
+
+ <p>A specially crafted sequence of HTTP/2 requests could trigger high CPU
+ usage for several seconds. If a sufficient number of such requests were
+ made on concurrent HTTP/2 connections, the server could become
+ unresponsive.</p>
+
+ <p>This was fixed with commit
+ <hashlink hash="9a0231683a77e2957cea0fdee88b193b30b0c976"/>.</p>
+
+ <p>This issue was reported publicly via the Apache Tomcat Users mailing
list
+ on 21 May 2020 without reference to the potential for DoS. The DoS risks
+ were identified by the Apache Tomcat Security Team the same day. The
+ issue was made public on 25 June 2020.</p>
