{"id":"CVE-2023-34967","url":"https://www.cyber-defence.io/tools/cve/CVE-2023-34967","generatedAt":"2026-11-04T23:11:14.323Z","title":"A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight.","description":"A Type Confusion vulnerability was found in Samba's mdssvc RPC service for Spotlight. 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.","published":"2023-07-20T15:15:11.000Z","lastModified":"2026-06-17T06:04:11.000Z","status":"Modified","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"cwe":["CWE-843"],"affected":["samba/samba","fedoraproject/fedora","redhat/enterprise linux","debian/debian linux"],"epss":{"score":0.61199,"percentile":0.99163,"date":"2026-11-03","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 61.2%, higher than 99% of all known CVEs.
