Target Milestone: ---
Classification: Other
A flaw was found in the Apache Tomcat, where the payload length in a WebSocket
frame was not correctly validated. Invalid payload lengths could trigger an
infinite loop. Multiple requests with invalid payload lengths could lead to a
denial of service.
It affects the version of Apache Tomcat 10.0.0-M1 to 10.0.0-M6, Apache Tomcat
9.0.0.M1 to 9.0.36, Apache Tomcat 8.5.0 to 8.5.56, and Apache Tomcat 7.0.27 to
7.0.104.
