Oracle Linux: CVE-2024-27983: ELSA-2024-2853: nodejs:20 security update (IMPORTANT) (Multiple Advisories)

Description

An attacker can make the Node.js HTTP/2 server completely 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. A vulnerability was found in how Node.js implements the HTTP/2 protocol. There are insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single stream. This issue could allow an unauthenticated, remote attacker to send packets to vulnerable servers, which could use up compute or memory resources, causing a denial of service.
