Description

In Apache Tomcat 9.0.0.M1 to 9.0.0.M18 and 8.5.0 to 8.5.12, the handling of an HTTP/2 GOAWAY frame for a connection did not close streams associated with that connection that were currently waiting for a WINDOW_UPDATE before allowing the application to write more data. These waiting streams each consumed a thread. A malicious client could therefore construct a series of HTTP/2 requests that would consume all available processing threads.

Affected configurations

• apache tomcat 8.5.0 • apache tomcat 8.5.1 • apache tomcat 8.5.2 • apache tomcat 8.5.3 • apache tomcat 8.5.4 • apache tomcat 8.5.5 • apache tomcat 8.5.6 • apache tomcat 8.5.7 • apache tomcat 8.5.8 • apache tomcat 8.5.9 • apache tomcat 8.5.10 • apache tomcat 8.5.11 • apache tomcat 8.5.12 • apache tomcat 9.0.0
