Opened: Nov 19, 2019
Severity: 3-Major

Symptoms

Invalid pseudo header or malformed header in an HTTP/3 request should result in resetting of the stream with error code of HTTP3_GENERAL_PROTOCOL_ERROR. Instead the connection is reset with HTTP3_UNEXPECTED_FRAME error code.

Impact

Connection is reset with incorrect error code, instead of just the individual stream.

Conditions

-- Virtual server with QUIC, HTTP/3, HTTP, SSL, and httprouter profiles. -- HTTP/3 header frame from client with invalid or malformed header is received.

Workaround

No workaround.

Fix Information

Correct return code is now propagated from the parser function.
