GHSA-w8gf-g2vq-j2f4 · amphp/http-client Denial of Service via HTTP/2 CONTINUATION Frames

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Early versions of `amphp/http-client` with HTTP/2 support (v4.0.0-rc10 to 4.0.0) will collect HTTP/2 `CONTINUATION` frames in an unbounded buffer and will not check the header size limit until it has received the `END_HEADERS` flag, resulting in an OOM crash. Later versions of `amphp/http-client` (v4.1.0-rc1 and up) depend on `amphp/http` for HTTP/2 processing and will therefore need an updated version of `amphp/http`, see [GHSA-qjfw-cvjf-f4fm](https://github.com/amphp/http/security/advisories/GHSA-qjfw-cvjf-f4fm). ## Acknowledgements Thank you to [Bartek Nowotarski](https://nowotarski.info/) for reporting the vulnerability.
