CVE-2019-10072 -- tomcat8, tomcat9
The fix for CVE-2019-0199 was incomplete and did not address HTTP/2 connection window exhaustion on write in Apache Tomcat versions 9.0.0.M1 to 9.0.19 and 8.5.0 to 8.5.40 . By not sending WINDOW_UPDATE messages for the connection window clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS.
