NVD Description

Note: Versions mentioned in the description apply only to the upstream falco-no-driver package and not the falco-no-driver package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

Historically, we have been rather lax about malformed framing-related headers in our HTTP/2 implementation, as they cannot interfere with HTTP/2 framing. However, this makes it possible for our HTTP/2 implementation to forward responses containing such headers to an HTTP/1 client when acting as a reverse proxy. If the HTTP/1 client also does not behave strictly enough, this can result in response smuggling.
