Vulnerability from github – Published: 2024-04-03 18:06 – Updated: 2024-05-02 18:58

Summary

AMPHP Denial of Service via HTTP/2 CONTINUATION Frames

Details

amphp/http 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. amphp/http-client and amphp/http-server are indirectly affected if they're used with an unpatched version of amphp/http. Early versions of amphp/http-client with HTTP/2 support (v4.0.0-rc10 to 4.0.0) are also directly affected.
