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.
Thank you to Bartek Nowotarski for reporting the vulnerability.
