CVE-2023-34967Samba: type confusion in mdssvc rpc service for spotlight

Red Hat Red Hat Enterprise Linux 8; Red Hat Red Hat Enterprise Linux 8.6 Extended Update Support; Red Hat Red Hat Enterprise Linux 8.8 Extended Update Support;… Veröffentlicht: (vor 3 Jahren)

Beschreibung

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.
