Assigner: GitHub_M
Published: 2021-09-09T22:05:11
State: PUBLISHED
affected: product: pomerium
vendor: pomerium
versions: status: affected
version: >= 0.15.0, < 0.15.1
descriptions: value: 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.
