SCA: security update for io.undertow:undertow-core (GHSA-w6qf-42m7-vh68)

high Tenable Self-Hosted Container Security Plugin ID 421465

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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. (CVE-2024-1635)

Solution

Update the io.undertow:undertow-core library and its related packages to version 2.2.31.Final or later.
