F5-K000139532: Race Condition

First published: Tue May 07 2024(Updated: )

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.

Affected Software	Affected Version	How to fix
F5 BIG-IP	>=17.1.0<=17.1.1
F5 BIG-IP	>=16.1.0<=16.1.4
F5 BIG-IP	>=15.1.0<=15.1.10
