Kerentanan Improper Check for Unusual or Exceptional Conditions pada envoyproxy envoy, pomerium. Skor CVSS 3.1 8.6 (High) menurut github.com.

Deskripsi (NVD)

Pomerium is an open source identity-aware access proxy. Envoy, which Pomerium is based on, can abnormally terminate if an H/2 GOAWAY and SETTINGS frame are received in the same IO event. This can lead to a DoS in the presence of untrusted *upstream* servers. 0.15.1 contains an upgraded envoy binary with this vulnerability patched. If only trusted upstreams are configured, there is not substantial risk of this condition being triggered.
