CVE-2017-5650

HIGH

Apache Tomcat 8.5.0-8.5.12 and 9.0.0.M1-9.0.0.M18 - Denial of Service via HTTP/2 GOAWAY Frame Handling

Title source: llm
STIX 2.1

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.
