La característica de compresión LZVN en AppleFSCompression en Apple OS X anterior a 10.10.4 permite a atacantes obtener información sensible de la estructura de la memoria para el kernel a través de una aplicación manipulada.

This vulnerability allows remote attackers to execute arbitrary code 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 DMG files. The issue lies in the handling of LZVN compressed streams. An attacker can leverage this vulnerability to leak the sensitive contents of physical memory.
