QID 982258: Java (maven) Security Update for org.apache.tomcat.embed:tomcat-embed-core (GHSA-q4hg-rmq2-52q9)

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 (stream 0) clients were able to cause server-side threads to block eventually leading to thread exhaustion and a DoS.

Successful exploitation of this vulnerability may affect the confidentiality, integrity, and availability of the targeted user.
