In Nanopb before versions 0.4.4 and 0.3.9.7, decoding specifically formed message can leak memory if dynamic allocation is enabled and an oneof field contains a static submessage that contains a dynamic field, and the message being decoded contains the submessage multiple times. This is rare in normal messages, but it is a concern when untrusted data is parsed. This is fixed in versions 0.3.9.7 and 0.4.4. The following workarounds are available: 1) Set the option `no_unions` for the oneof field. This will generate fields as separate instead of C union, and avoids triggering the problematic code. 2) Set the type of the submessage field inside oneof to `FT_POINTER`. This way the whole submessage will be dynamically allocated and the problematic code is not executed. 3) Use an arena allocator for nanopb, to make sure all memory can be released afterwards.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/16856"}, {"timestamp": "2020-12-07T20:49:00Z", "date_only": false, "value": "2020-12-07T20:49Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2020-26243", "record": "GSD-2020-26243", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2021-01-07T00:00:00Z", "date_only": true, "value": "2021-01-07", "kind": "other", "label": "Date", "source": "gsd \u00b7 GSD-2020-26243", "record": "GSD-2020-26243", "field": "namespaces.gitlab.com.advisories.0.date"}, {"timestamp": "2021-01-07T22:39:39Z", "date_only": false, "value": "2021-01-07T22:39:39Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-85RR-4RH9-HHWH", "record": "GHSA-85RR-4RH9-HHWH", "field": "modified"}, {"timestamp": "2023-12-13T01:22:08.917Z", "date_only": false, "value": "2023-12-13T01:22:08.917385Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2020-26243", "record": "GSD-2020-26243", "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": "2024-08-04T15:56:04.801Z", "date_only": false, "value": "2024-08-04T15:56:04.801Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2020-26243", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-04T15:56:04.801Z", "date_only": false, "value": "2024-08-04T15:56:04.801Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2020-26243", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-04-22T07:39:34Z", "date_only": false, "value": "2026-04-22T07:39:34Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2020-26243", "record": "UBUNTU-CVE-2020-26243", "field": "modified"}, {"timestamp": "2026-06-17T03:07:54.293Z", "date_only": false, "value": "2026-06-17T03:07:54.293", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2020-26243", "record": "FKIE_CVE-2020-26243", "field": "lastModified"}, {"timestamp": "2026-07-02T14:13:09.752Z", "date_only": false, "value": "2026-07-02T14:13:09.752037Z", "kind": "milestone", "label": "Published", "source": "pysec \u00b7 PYSEC-2026-684", "record": "PYSEC-2026-684", "field": "published"}, {"timestamp": "2026-07-06T07:36:56.538Z", "date_only": false, "value": "2026-07-06T07:36:56.538147Z", "kind": "other", "label": "Updated", "source": "pysec \u00b7 PYSEC-2026-684", "record": "PYSEC-2026-684", "field": "modified"}, {"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"}]}
