Al solicitar una nueva contrase\u00f1a, Shadow-Utils la solicita dos veces. Si la contrase\u00f1a falla en el segundo intento, Shadow-Utils no logra limpiar el b\u00fafer utilizado para almacenar la primera entrada. Esto puede permitir que un atacante con suficiente acceso recupere la contrase\u00f1a de la memoria."}], "id": "CVE-2023-4641", "lastModified": "2026-06-17T06:38:16.850", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "HIGH", "attackVector": "LOCAL", "availabilityImpact": "NONE", "baseScore": 4.7, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N", "version": "3.1"}, "exploitabilityScore": 1.0, "impactScore": 3.6, "source": "secalert@redhat.com", "type": "Secondary"}, {"cvssData": {"attackComplexity": "LOW", "attackVector": "LOCAL", "availabilityImpact": "NONE", "baseScore": 5.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "HIGH", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N", "version": "3.1"}, "exploitabilityScore": 1.8, "impactScore": 3.6, "source": "nvd@nist.gov", "type": "Primary"}], "ssvcV203": [{"source": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "ssvcData": {"id": "CVE-2023-4641", "options": [{"exploitation": "none"}, {"automatable": "no"}, {"technicalImpact": "total"}], "role": "CISA Coordinator", "timestamp": "2024-01-02T18:19:24.685793Z", "version": "2.0.3"}}]}, "published": "2023-12-27T16:15:13.363", "references": [{"source": "secalert@redhat.com", "tags": ["Third Party Advisory"], "url": "https://access.redhat.com/errata/RHSA-2023:6632"}, {"source": "secalert@redhat.com", "tags": ["Third Party Advisory"], "url": "https://access.redhat.com/errata/RHSA-2023:7112"}, {"source": "secalert@redhat.com", "url": "https://access.redhat.com/errata/RHSA-2024:0417"}, {"source": "secalert@redhat.com", "url": "https://access.redhat.com/errata/RHSA-2024:2577"}, {"source": "secalert@redhat.com", "tags": ["Third Party Advisory"], "url": "https://access.redhat.com/security/cve/CVE-2023-4641"}, {"source": "secalert@redhat.com", "tags": ["Issue Tracking"], "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2215945"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Third Party Advisory"], "url": "https://access.redhat.com/errata/RHSA-2023:6632"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Third Party Advisory"], "url": "https://access.redhat.com/errata/RHSA-2023:7112"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://access.redhat.com/errata/RHSA-2024:0417"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://access.redhat.com/errata/RHSA-2024:2577"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Third Party Advisory"], "url": "https://access.redhat.com/security/cve/CVE-2023-4641"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "tags": ["Issue Tracking"], "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2215945"}, {"source": "af854a3a-2127-422b-91ae-364da2661108", "url": "https://lists.debian.org/debian-lts-announce/2025/04/msg00026.html"}], "sourceIdentifier": "secalert@redhat.com", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-303"}], "source": "secalert@redhat.com", "type": "Secondary"}, {"description": [{"lang": "en", "value": "CWE-287"}], "source": "nvd@nist.gov", "type": "Primary"}]}
