After 2^64 (~18.4 quintillion) messages are encrypted with the Encrypt function, the nonce counter will wrap around, causing multiple messages to be encrypted with the same key and nonce. In a separate issue, the Decrypt function increments the nonce state even when it fails to decrypt a message. If an attacker can provide an invalid input to the Decrypt function, this will cause the nonce state to desynchronize between the peers, resulting in a failure to encrypt all subsequent messages.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/55454"}, {"timestamp": "2022-12-28T00:30:23Z", "date_only": false, "value": "2022-12-28T00:30:23Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-6CR6-FMVC-VW2P", "record": "GHSA-6CR6-FMVC-VW2P", "field": "published"}, {"timestamp": "2022-12-29T00:00:00Z", "date_only": true, "value": "2022-12-29", "kind": "other", "label": "Date", "source": "gsd \u00b7 GSD-2021-4239", "record": "GSD-2021-4239", "field": "namespaces.gitlab.com.advisories.0.date"}, {"timestamp": "2023-01-06T01:30:00Z", "date_only": false, "value": "2023-01-06T01:30Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-4239", "record": "GSD-2021-4239", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2023-02-09T21:41:23Z", "date_only": false, "value": "2023-02-09T21:41:23Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-6CR6-FMVC-VW2P", "record": "GHSA-6CR6-FMVC-VW2P", "field": "modified"}, {"timestamp": "2023-06-12T19:04:19.549Z", "date_only": false, "value": "2023-06-12T19:04:19.549Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / Go", "record": "CVE-2021-4239", "field": "containers.cna.providerMetadata.dateUpdated"}, {"timestamp": "2023-12-13T01:23:11.820Z", "date_only": false, "value": "2023-12-13T01:23:11.820804Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-4239", "record": "GSD-2021-4239", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-08-03T17:23:10.118Z", "date_only": false, "value": "2024-08-03T17:23:10.118Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2021-4239", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2025-04-14T16:59:11.062Z", "date_only": false, "value": "2025-04-14T16:59:11.062582Z", "kind": "other", "label": "Recorded", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2021-4239", "field": "containers.adp.1.metrics.1.other.content.timestamp"}, {"timestamp": "2025-04-14T16:59:11.062Z", "date_only": false, "value": "2025-04-14T16:59:11.062582Z", "kind": "other", "label": "Recorded", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-4239", "record": "FKIE_CVE-2021-4239", "field": "metrics.ssvcV203.0.ssvcData.timestamp"}, {"timestamp": "2025-04-14T16:59:43.688Z", "date_only": false, "value": "2025-04-14T16:59:43.688Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2021-4239", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2025-04-14T16:59:43.688Z", "date_only": false, "value": "2025-04-14T16:59:43.688Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CISA-ADP", "record": "CVE-2021-4239", "field": "containers.adp.1.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T04:19:19.820Z", "date_only": false, "value": "2026-06-17T04:19:19.820", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-4239", "record": "FKIE_CVE-2021-4239", "field": "lastModified"}, {"timestamp": "2026-10-17T09:08:06Z", "date_only": false, "value": "2026-10-17T09:08:06Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2021-4239", "record": "UBUNTU-CVE-2021-4239", "field": "modified"}]}
