Doc Type: If docs needed, set a value
Doc Text:
A vulnerability was found in how amphp 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 to cause a Denial of Service.

Description Nick Tait 2024-03-12 15:39:44 UTC 
This description was provided in the disclosure from VINCE:

The AMPHP implementation of HTTP/2 will collect CONTINUATION frames in an unbounded buffer and will not check a limit until it has received the set END_HEADERS flag, resulting in an OOM crash.
