When parsing Spotlight mdssvc RPC packets, one encoded data structure is a key-value style dictionary where the keys are character strings, and the values can be any of the supported types in the mdssvc protocol. Due to a lack of type checking in callers of the dalloc_value_for_key() function, which returns the object associated with a key, a caller may trigger a crash in talloc_get_size() when talloc detects that the passed-in pointer is not a valid talloc pointer. With an RPC worker process shared among multiple client connections, a malicious client or attacker can trigger a process crash in a shared RPC mdssvc worker process, affecting all other clients this worker serves." } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "Access of Resource Using Incompatible Type ('Type Confusion')", "cweId": "CWE-843" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Red Hat", "product": { "product_data": [ { "product_name": "Red Hat Enterprise Linux 8", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:4.18.6-1.el8", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:4.18.6-1.el8", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 8.6 Extended Update Support", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:4.15.5-15.el8_6", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 8.8 Extended Update Support", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:4.17.5-5.el8_8", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 9", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:4.18.6-100.el9", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:4.18.6-100.el9", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Virtualization 4 for Red Hat Enterprise Linux 8", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "versions": [ { "version": "0:4.15.5-15.el8_6", "lessThan": "*", "versionType": "rpm", "status": "unaffected" } ], "defaultStatus": "affected" } } ] } }, { "product_name": "Red Hat Enterprise Linux 6", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unknown" } }, { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unknown" } } ] } }, { "product_name": "Red Hat Enterprise Linux 7", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "unknown" } } ] } }, { "product_name": "Red Hat Storage 3", "version": { "version_data": [ { "version_value": "not down converted", "x_cve_json_5_version_data": { "defaultStatus": "affected" } } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://access.redhat.com/errata/RHSA-2023:6667", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2023:6667" }, { "url": "https://access.redhat.com/errata/RHSA-2023:7139", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2023:7139" }, { "url": "https://access.redhat.com/errata/RHSA-2024:0423", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:0423" }, { "url": "https://access.redhat.com/errata/RHSA-2024:0580", "refsource": "MISC", "name": "https://access.redhat.com/errata/RHSA-2024:0580" }, { "url": "https://access.redhat.com/security/cve/CVE-2023-34967", "refsource": "MISC", "name": "https://access.redhat.com/security/cve/CVE-2023-34967" }, { "url": "https://bugzilla.redhat.com/show_bug.cgi?id=2222794", "refsource": "MISC", "name": "https://bugzilla.redhat.com/show_bug.cgi?id=2222794" }, { "url": "https://www.samba.org/samba/security/CVE-2023-34967.html", "refsource": "MISC", "name": "https://www.samba.org/samba/security/CVE-2023-34967.html" } ] }, "work_around": [ { "lang": "en", "value": "As a possible workaround, disable Spotlight by removing all configuration stanzas (\"spotlight=yes|true\") that enable Spotlight ." } ], "impact": { "cvss": [ { "attackComplexity": "LOW", "attackVector": "NETWORK", "availabilityImpact": "LOW", "baseScore": 5.3, "baseSeverity": "MEDIUM", "confidentialityImpact": "NONE", "integrityImpact": "NONE", "privilegesRequired": "NONE", "scope": "UNCHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L", "version": "3.1" } ] } }
