Описание
The payload length in a WebSocket frame was not correctly validated in Apache Tomcat 10.0.0-M1 to 10.0.0-M6, 9.0.0.M1 to 9.0.36, 8.5.0 to 8.5.56 and 7.0.27 to 7.0.104. Invalid payload lengths could trigger an infinite loop. Multiple requests with invalid payload lengths could lead to a denial of service.
A flaw was found in 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. The highest threat from this vulnerability is to system availability.
Отчет
Red Hat Certificate System 10.0 as well as Red Hat Enterprise Linux 8's Identity Management, are using a vulnerable version of Tomcat, bundled into the pki-servlet-engine component. However, there is no entry point for WebSockets, thus it is not possible to trigger the flaw in a supported setup. A future update may fix the code. Similarly, Red Hat OpenStack Platform 13 does not ship with WebSocket functionality enabled by default.
Меры по смягчению последствий
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update as soon as possible.
