公告说明

Envoy, which Pomerium is based on, can abnormally terminate if an H/2 GOAWAY and SETTINGS frame are received in the same IO event.

Impact

This can lead to a DoS in the presence of untrusted upstream servers.

Patches

0.15.1 contains an upgraded envoy binary with this vulnerability patched.

Workarounds

If only trusted upstreams are configured, there is not substantial risk of this condition being triggered.
