Summary
A vulnerability was found in Undertow. This vulnerability impacts a server that supports the wildfly-http-client protocol. Whenever a malicious user opens and closes a connection with the HTTP port of the server and then closes the connection immediately, the server will end with both memory and open file limits exhausted at some point, depending on the amount of memory available. At HTTP upgrade to remoting, the WriteTimeoutStreamSinkConduit leaks connections if RemotingConnection is closed by Remoting ServerConnectionOpenListener. Because the remoting connection originates in Undertow as part of the HTTP upgrade, there is an external layer to the remoting connection. This connection is unaware of the outermost layer when closing the connection during the connection opening procedure. Hence, the Undertow WriteTimeoutStreamSinkConduit is not notified of the closed connection in this scenario. Because WriteTimeoutStreamSinkConduit creates a timeout task, the whole dependency tree leaks via that task, which is added to XNIO WorkerThread. So, the workerThread points to the Undertow conduit, which contains the connections and causes the leak.

         value: "Se encontró una vulnerabilidad en Undertow. Esta vulnerabilidad afecta a un servidor que admite el protocolo wildfly-http-client. Siempre que un usuario malintencionado abre y cierra una conexión con el puerto HTTP del servidor y luego cierra la conexión inmediatamente, el servidor finalizará con los límites de memoria y de archivos abiertos agotados en algún momento, dependiendo de la cantidad de memoria disponible. En la actualización HTTP a comunicación remota, WriteTimeoutStreamSinkConduit pierde conexiones si RemotingConnection se cierra mediante Remoting ServerConnectionOpenListener. Debido a que la conexión remota se origina en Undertow como parte de la actualización HTTP, existe una capa externa a la conexión remota. Esta conexión desconoce la capa más externa al cerrar la conexión durante el procedimiento de apertura de la conexión. Por lo tanto, Undertow WriteTimeoutStreamSinkConduit no recibe notificación de la conexión cerrada en este escenario. Debido a que WriteTimeoutStreamSinkConduit crea una tarea de tiempo de espera, todo el árbol de dependencia se filtra a través de esa tarea, que se agrega a XNIO WorkerThread. Entonces, el hilo de trabajo apunta al conducto Undertow, que contiene las conexiones y causa la fuga.",
