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.

Affected configurations

• apache tomcat (>= 8.5.0 <= 8.5.40) • apache tomcat (>= 9.0.1 <= 9.0.19) • apache tomcat 9.0.0
