Overview
Affected versions of this package are vulnerable to Detection of Error Condition Without Action due to HTTP/2 codec not resetting a request when header map limits have been exceeded. This allows an attacker to send an sequence of CONTINUATION frames without the END_HEADERS bit set causing unlimited memory consumption.

Workaround
Downgrade to version 1.28.1 or earlier or disable HTTP/2 protocol for downstream connections.
