CVSS: 7.5EPSS: 0%CPEs: 6EXPL: 0CVE-2021-39204 – Excessive CPU usage in Pomerium
https://notcve.org/view.php?id=CVE-2021-39204
Pomerium is an open source identity-aware access proxy. Envoy, which Pomerium is based on, incorrectly handles resetting of HTTP/2 streams with excessive complexity. This can lead to high CPU utilization when a large number of streams are reset. This can result in a DoS condition. Pomerium versions 0.14.8 and 0.15.1 contain an upgraded envoy binary with this vulnerability patched. • https://github.com/envoyproxy/envoy/security/advisories/GHSA-3xh3-33v5-chcc https://github.com/pomerium/pomerium/security/advisories/GHSA-5wjf-62hw-q78r https://groups.google.com/g/envoy-announce/c/5xBpsEZZDfE/m/wD05NZBbAgAJ • CWE-834: Excessive Iteration •
CVSS: 8.6EPSS: 0%CPEs: 3EXPL: 0CVE-2021-39162 – Incorrect handling of H2 GOAWAY + SETTINGS frames
https://notcve.org/view.php?id=CVE-2021-39162
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.
