In Nanopb before versions 0.3.9.8 and 0.4.5, decoding a specifically formed message can cause invalid `free()` or `realloc()` calls if the message type contains an `oneof` field, and the `oneof` directly contains both a pointer field and a non-pointer field. If the message data first contains the non-pointer field and then the pointer field, the data of the non-pointer field is incorrectly treated as if it was a pointer value. Such message data rarely occurs in normal messages, but it is a concern when untrusted data is parsed. This has been fixed in versions 0.3.9.8 and 0.4.5. See referenced GitHub Security Advisory for more information including workarounds.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/25334"}, {"timestamp": "2021-03-29T14:50:00Z", "date_only": false, "value": "2021-03-29T14:50Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-21401", "record": "GSD-2021-21401", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2021-11-24T22:47:12.152Z", "date_only": false, "value": "2021-11-24T22:47:12.152718Z", "kind": "other", "label": "Updated", "source": "pysec \u00b7 PYSEC-2021-432", "record": "PYSEC-2021-432", "field": "modified"}, {"timestamp": "2023-12-13T01:23:10.870Z", "date_only": false, "value": "2023-12-13T01:23:10.870487Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-21401", "record": "GSD-2021-21401", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-06-15T00:00:00Z", "date_only": false, "value": "2024-06-15T00:00:00Z", "kind": "other", "label": "Advisory revision", "source": "csaf_opensuse \u00b7 OPENSUSE-SU-2024:11074-1", "record": "OPENSUSE-SU-2024:11074-1", "field": "document.tracking.revision_history.0.date"}, {"timestamp": "2024-06-15T00:00:00Z", "date_only": false, "value": "2024-06-15T00:00:00Z", "kind": "other", "label": "Date", "source": "csaf_opensuse \u00b7 OPENSUSE-SU-2024:11074-1", "record": "OPENSUSE-SU-2024:11074-1", "field": "vulnerabilities.0.threats.0.date"}, {"timestamp": "2024-06-15T00:00:00Z", "date_only": false, "value": "2024-06-15T00:00:00Z", "kind": "other", "label": "Document generated", "source": "csaf_opensuse \u00b7 OPENSUSE-SU-2024:11074-1", "record": "OPENSUSE-SU-2024:11074-1", "field": "document.tracking.generator.date"}, {"timestamp": "2024-06-15T00:00:00Z", "date_only": false, "value": "2024-06-15T00:00:00Z", "kind": "milestone", "label": "Published", "source": "csaf_opensuse \u00b7 OPENSUSE-SU-2024:11074-1", "record": "OPENSUSE-SU-2024:11074-1", "field": "document.tracking.initial_release_date"}, {"timestamp": "2024-08-03T18:09:16.087Z", "date_only": false, "value": "2024-08-03T18:09:16.087Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2021-21401", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-03T18:09:16.087Z", "date_only": false, "value": "2024-08-03T18:09:16.087Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2021-21401", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-08-30T18:45:41Z", "date_only": false, "value": "2024-08-30T18:45:41Z", "kind": "milestone", "label": "Published", "source": "github \u00b7 GHSA-7MV5-5MXH-QG88", "record": "GHSA-7MV5-5MXH-QG88", "field": "published"}, {"timestamp": "2024-08-30T18:45:41Z", "date_only": false, "value": "2024-08-30T18:45:41Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-7MV5-5MXH-QG88", "record": "GHSA-7MV5-5MXH-QG88", "field": "modified"}, {"timestamp": "2026-04-22T07:39:54Z", "date_only": false, "value": "2026-04-22T07:39:54Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2021-21401", "record": "UBUNTU-CVE-2021-21401", "field": "modified"}, {"timestamp": "2026-06-17T03:35:29.647Z", "date_only": false, "value": "2026-06-17T03:35:29.647", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-21401", "record": "FKIE_CVE-2021-21401", "field": "lastModified"}, {"timestamp": "2026-09-20T20:10:48Z", "date_only": false, "value": "2026-09-20T20:10:48Z", "kind": "other", "label": "Advisory revision", "source": "csaf_opensuse \u00b7 OPENSUSE-SU-2024:11074-1", "record": "OPENSUSE-SU-2024:11074-1", "field": "document.tracking.revision_history.1.date"}, {"timestamp": "2026-09-20T20:10:48Z", "date_only": false, "value": "2026-09-20T20:10:48Z", "kind": "other", "label": "Updated", "source": "csaf_opensuse \u00b7 OPENSUSE-SU-2024:11074-1", "record": "OPENSUSE-SU-2024:11074-1", "field": "document.tracking.current_release_date"}]}
