Denial of Service (DoS)

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Denial of Service (DoS) when processing a crafted HTTP/2 request. If the request exceeded any of the configured limits for headers, the associated HTTP/2 stream was not reset until after all of the headers had been processed.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat:tomcat-coyote to version 8.5.99, 9.0.86, 10.1.19, 1.0.0-M17 or higher.

Improper Input Validation

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Improper Input Validation due to the improper handling of HTTP trailer headers. An attacker can manipulate the server into treating a single request as multiple requests by sending a specially crafted, invalid trailer header. This could lead to request smuggling when the server is behind a reverse proxy.

How to fix Improper Input Validation?

Upgrade org.apache.tomcat:tomcat-coyote to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

[8.5.0,8.5.94) [9.0.0-M1,9.0.81) [10.1.0-M1,10.1.14) [11.0.0-M1,11.0.0-M12)

Denial of Service (DoS)

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Denial of Service (DoS) in the implementation of the HTTP/2 protocol. An attacker can cause a denial of service (including via DDoS) by rapidly resetting many streams through request cancellation.

How to fix Denial of Service (DoS)?

Upgrade org.apache.tomcat:tomcat-coyote to version 8.5.94, 9.0.81, 10.1.14, 11.0.0-M12 or higher.

Improper Resource Shutdown or Release

org.apache.tomcat:tomcat-coyote is a Tomcat Connectors and HTTP parser.

Affected versions of this package are vulnerable to Improper Resource Shutdown or Release. When a web application sends a WebSocket message concurrently with the WebSocket connection closing, the application may continue to use the socket after it has been closed. This could result in subsequent connections using the same object concurrently which could result in data being returned to the wrong use and/or other errors.

How to fix Improper Resource Shutdown or Release?

Upgrade org.apache.tomcat:tomcat-coyote to version 8.5.76, 9.0.21 or higher.
