Doc Text:
A vulnerability was found in how Envoy Proxy implements the oghttp codec. 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 memory resources to cause a Denial of Service.

Description Nick Tait 2024-03-13 22:38:27 UTC
Envoy is vulnerable to a DoS caused by how it continues to receive CONTINUATION frames, and will not callback to the application to allow visibility into this information before it resets the stream.
