NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs-devel package and not the nodejs-devel package as distributed by Oracle. See How to fix? for Oracle:8 relevant fixed versions and status.

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.
