{"id":"BIT-envoy-2022-23606","summary":"Crash when a cluster is deleted in Envoy","details":"Envoy is an open source edge and service proxy, designed for cloud-native applications. When a cluster is deleted via Cluster Discovery Service (CDS) all idle connections established to endpoints in that cluster are disconnected. A recursion was introduced in the procedure of disconnecting idle connections that can lead to stack exhaustion and abnormal process termination when a cluster has a large number of idle connections. This infinite recursion causes Envoy to crash. Users are advised to upgrade.","aliases":["CVE-2022-23606","GHSA-9vp2-4cp7-vvxf"],"modified":"2026-09-08T08:47:23.765313428Z","published":"2024-03-06T10:55:43.299Z","database_specific":{"severity":"Medium","cpes":["cpe:2.3:a:envoyproxy:envoy:*:*:*:*:*:*:*:*","cpe:2.3:a:envoyproxy:envoy:1.21.0:*:*:*:*:*:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/commit/4b6dd3b53cd5c6d4d4df378a2fc62c1707522b31"},{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-9vp2-4cp7-vvxf"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23606"}],"affected":[{"package":{"name":"envoy","ecosystem":"Bitnami","purl":"pkg:bitnami/envoy"},"ranges":[{"type":"SEMVER","events":[{"introduced":"1.20.0"},{"fixed":"1.20.2"},{"introduced":"1.21.0"},{"fixed":"1.21.1"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/envoy/BIT-envoy-2022-23606.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.9.0"}
