Descriptions

Audio in Apple OS X before 10.11.6 mishandles a size value, which allows remote attackers to obtain sensitive information or cause a denial of service (out-of-bounds read) via a crafted audio file.

Audio en Apple OS X en versiones anteriores a 10.11.6 no maneja correctamente un valor de tamaño, lo que permite a atacantes remotos obtener información sensible o provocar una denegación de servicio (lectura fuera de rango) a través de una archivo de audio manipulado.

This vulnerability allows remote attackers to leak sensitive information on vulnerable installations of Apple OS X. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the handling of MOV files. The issue lies in the failure to validate a user-supplied value prior to using it as the size parameter in a call to memcpy. An attacker can leverage this vulnerability to leak sensitive information in the context of the current process.
