Descriptions

Heap-based buffer overflow in Apple Type Services (ATS) in Apple Mac OS X 10.4.11 and 10.5 before 10.5.7 allows remote attackers to execute arbitrary code via a crafted Compact Font Format (CFF) font.

Desbordamiento de búfer basado en pila en Apple Type Services (ATS) en Apple Mac OS X v10.4.11 y v10.5 antes de v10.5.7 permite a atacantes remotos ejecutar código arbitrario a través de una fuente Compact Font Format (CFF) elaborada.

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 appears to exist in the ATSServer font server upon parsing of malicious Compact Font Format files. A boundary condition exists in the parsing of internal dictionaries that can lead to a memory corruption allowing the execution of arbitrary code.
