Una vulnerabilidad de cruce de enlaces simb\u00f3licos en la librer\u00eda de contenedores/almacenamiento puede hacer que Podman, Buildah y CRI-O se bloqueen y generen una denegaci\u00f3n de servicio mediante la eliminaci\u00f3n de OOM al ejecutar una imagen maliciosa utilizando un espacio de nombres de usuario asignado autom\u00e1ticamente (`--userns=auto` en Podman y Buildah). La librer\u00eda de contenedores/almacenamiento leer\u00e1 /etc/passwd dentro del contenedor, pero no validar\u00e1 correctamente si ese archivo es un enlace simb\u00f3lico, lo que se puede utilizar para hacer que la librer\u00eda lea un archivo arbitrario en el host."}], "id": "CVE-2024-9676", "lastModified": "2024-11-26T09:15:06.820", "metrics": {"cvssMetricV31": [{"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 6.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 2.8, "impactScore": 3.6, "source": "[email protected]", "type": "Secondary"}, {"cvssData": {"attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 6.5, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "LOW", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H", "version": "3.1"}, "exploitabilityScore": 2.8, "impactScore": 3.6, "source": "[email protected]", "type": "Primary"}]}, "published": "2024-10-15T16:15:06.933", "references": [{"source": "[email protected]", "url": "https://access.redhat.com/errata/RHSA-2024:10289"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8418"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8428"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8437"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8686"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8690"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8694"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8700"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:8984"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:9051"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:9454"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:9459"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/errata/RHSA-2024:9926"}, {"source": "[email protected]", "tags": ["Vendor Advisory"], "url": "https://access.redhat.com/security/cve/CVE-2024-9676"}, {"source": "[email protected]", "tags": ["Issue Tracking"], "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2317467"}, {"source": "[email protected]", "tags": ["Third Party Advisory"], "url": "https://github.com/advisories/GHSA-wq2p-5pc6-wpgf"}], "sourceIdentifier": "[email protected]", "vulnStatus": "Modified", "weaknesses": [{"description": [{"lang": "en", "value": "CWE-22"}], "source": "[email protected]", "type": "Secondary"}]}
