REDHAT-BUG-2272764: Race Condition

First published: Tue Apr 02 2024(Updated: )

At a minimum, the following versions of Node.js are affected 18, 20, and 21. Description: An attacker can make the Node.js HTTP/2 server unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.
