NVD Description

Note: Versions mentioned in the description apply only to the upstream tomcat8 package and not the tomcat8 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

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.
