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.\n\n## Affected\n\n- `samba (all versions)`\n- `samba (all versions)`\n- `samba (all versions)`\n- `samba (all versions)`\n- `samba (all versions)`\n- `samba (all versions)`\n- `samba (all versions)`\n- `samba`\n- `samba4`\n- `samba`\n- `samba`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nAs a possible workaround, disable Spotlight by removing all configuration stanzas (\"spotlight=yes|true\") that enable Spotlight .","depth":"sunlit","depthScore":41,"depthScoreParts":{"impact":29.2,"likelihood":12.2,"exploitation":0,"ransomware":0},"changes":[]}
