{"id":"BIT-envoy-2021-39162","summary":"Incorrect handling of H2 GOAWAY + SETTINGS frames","details":"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.","aliases":["CVE-2021-39162","GHSA-gjcg-vrxg-xmgv","GO-2022-0933"],"modified":"2026-09-08T08:47:23.763744442Z","published":"2024-03-06T10:57:33.498Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:envoyproxy:envoy:*:*:*:*:*:*:*:*","cpe:2.3:a:envoyproxy:envoy:1.19.0:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-j374-mjrw-vvp8"},{"type":"ADVISORY","url":"https://github.com/pomerium/pomerium/security/advisories/GHSA-gjcg-vrxg-xmgv"},{"type":"ADVISORY","url":"https://groups.google.com/g/envoy-announce/c/5xBpsEZZDfE/m/wD05NZBbAgAJ"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2021-39162"}],"affected":[{"package":{"name":"envoy","ecosystem":"Bitnami","purl":"pkg:bitnami/envoy"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.18.4"},{"introduced":"1.19.0"},{"fixed":"1.19.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/envoy/BIT-envoy-2021-39162.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
