When parsing Spotlight 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 underlying 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 malicious actor may be able to fully control the value of the pointer and theoretically achieve Remote Code Execution on the host. This issue is similar to CVE-2023-34967."}, {"lang": "es", "value": "Se encontr\u00f3 una vulnerabilidad de Confusi\u00f3n de Tipos en las funciones Spotlight RPC en afpd en Netatalk 3.1.x anterior a 3.1.17.
