Affected packages

• Maven org.apache.tomcat.embed:tomcat-embed-core: >= 9.0.0.M1, < 9.0.20 → fixed in 9.0.20 • Maven org.apache.tomcat.embed:tomcat-embed-core: >= 8.5.0, < 8.5.41 → fixed in 8.5.41

Description

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.
