In affected versions envoy\u00e2\u20ac\u2122s procedure for resetting a HTTP/2 stream has O(N^2) complexity, leading to high CPU utilization when a large number of streams are reset. Deployments are susceptible to Denial of Service when Envoy is configured with high limit on H/2 concurrent streams. An attacker wishing to exploit this vulnerability would require a client opening and closing a large number of H/2 streams. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes to reduce time complexity of resetting HTTP/2 streams. As a workaround users may limit the number of simultaneous HTTP/2 dreams for upstream and downstream peers to a low number, i.e. 100.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/27851"}, {"timestamp": "2021-11-02T13:06:12Z", "date_only": false, "value": "2021-11-02T13:06:12+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_redhat \u00b7 RHEA-2021:4051", "record": "RHEA-2021:4051", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2021-11-02T13:06:12Z", "date_only": false, "value": "2021-11-02T13:06:12+00:00", "kind": "other", "label": "Date", "source": "csaf_redhat \u00b7 RHEA-2021:4051", "record": "RHEA-2021:4051", "field": "vulnerabilities.0.remediations.0.date"}, {"timestamp": "2021-11-02T13:06:12Z", "date_only": false, "value": "2021-11-02T13:06:12+00:00", "kind": "milestone", "label": "Published", "source": "csaf_redhat \u00b7 RHEA-2021:4051", "record": "RHEA-2021:4051", "field": "document.tracking.initial_release_date"}, {"timestamp": "2022-06-15T15:49:00Z", "date_only": false, "value": "2022-06-15T15:49Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-32778", "record": "GSD-2021-32778", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2023-12-13T01:23:09.147Z", "date_only": false, "value": "2023-12-13T01:23:09.147824Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-32778", "record": "GSD-2021-32778", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-03-06T10:58:13.992Z", "date_only": false, "value": "2024-03-06T10:58:13.992Z", "kind": "milestone", "label": "Published", "source": "bitnami_vulndb \u00b7 BIT-ENVOY-2021-32778", "record": "BIT-ENVOY-2021-32778", "field": "published"}, {"timestamp": "2024-08-03T23:33:55.854Z", "date_only": false, "value": "2024-08-03T23:33:55.854Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2021-32778", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-03T23:33:55.854Z", "date_only": false, "value": "2024-08-03T23:33:55.854Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2021-32778", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2025-11-21T17:24:24Z", "date_only": false, "value": "2025-11-21T17:24:24+00:00", "kind": "other", "label": "Advisory revision", "source": "csaf_redhat \u00b7 RHEA-2021:4051", "record": "RHEA-2021:4051", "field": "document.tracking.revision_history.2.date"}, {"timestamp": "2025-11-21T17:24:24Z", "date_only": false, "value": "2025-11-21T17:24:24+00:00", "kind": "other", "label": "Document generated", "source": "csaf_redhat \u00b7 RHEA-2021:4051", "record": "RHEA-2021:4051", "field": "document.tracking.generator.date"}, {"timestamp": "2025-11-21T17:24:24Z", "date_only": false, "value": "2025-11-21T17:24:24+00:00", "kind": "other", "label": "Updated", "source": "csaf_redhat \u00b7 RHEA-2021:4051", "record": "RHEA-2021:4051", "field": "document.tracking.current_release_date"}, {"timestamp": "2026-06-17T03:53:36.730Z", "date_only": false, "value": "2026-06-17T03:53:36.730", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-32778", "record": "FKIE_CVE-2021-32778", "field": "lastModified"}, {"timestamp": "2026-09-08T08:34:36.952Z", "date_only": false, "value": "2026-09-08T08:34:36.952Z", "kind": "other", "label": "Updated", "source": "bitnami_vulndb \u00b7 BIT-ENVOY-2021-32778", "record": "BIT-ENVOY-2021-32778", "field": "modified"}]}
