Descriptions

FontParser in Apple iOS before 8.1.3, Apple OS X before 10.10.2, and Apple TV before 7.0.3 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted .dfont file.

FontParser en Apple iOS anterior a 8.1.3, Apple OS X anterior a 10.10.2, y Apple TV anterior a 7.0.3 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria y caída de aplicación) a través de un fichero .dfont manipulado.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple Mac OSX. 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 parsing of a dfont file. When processing a malformed dfont file, a specified value is parsed from the file and passed to the memmove API call which can cause memory corruption. A remote attacker can use this to execute remote code under the context of the user.
