Descriptions

A Type Confusion vulnerability was found in the Spotlight RPC functions in afpd in Netatalk 3.1.x before 3.1.17. 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.

Se encontró una vulnerabilidad de Confusión de Tipos en las funciones Spotlight RPC en afpd en Netatalk 3.1.x anterior a 3.1.17. Al analizar paquetes RPC de Spotlight, una estructura de datos codificada es un diccionario de estilo clave-valor donde las claves son cadenas de caracteres y los valores pueden ser cualquiera de los tipos admitidos en el protocolo subyacente. Debido a la falta de verificación de tipos en las personas que llaman a la función dalloc_value_for_key(), que devuelve el objeto asociado con una clave, un actor malicioso puede controlar completamente el valor del puntero y, en teoría, lograr la Ejecución Remota de Código en el anfitrión. Este problema es similar a CVE-2023-34967.
