NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs:20/nodejs-packaging-bundler package and not the nodejs:20/nodejs-packaging-bundler package as distributed by AlmaLinux. See How to fix? for AlmaLinux:9 relevant fixed versions and status.

A malformed HTTP/2 HEADERS frame with oversized, invalid HPACK data can cause Node.js to crash by triggering an unhandled TLSSocket error ECONNRESET. Instead of safely closing the connection, the process crashes, enabling a remote denial of service. This primarily affects applications that do not attach explicit error handlers to secure sockets, for example:

server.on(&#39;secureConnection&#39;, socket =&gt; {
  socket.on(&#39;error&#39;, err =&gt; {
    console.log(err)
  })
})
