Descriptions

Multiple buffer overflows in Apple Type Services (ATS) in Apple Mac OS X before 10.6.7 allow remote attackers to execute arbitrary code via a document that contains a crafted embedded Type 1 font.

Múltiples desbordamientos de búfer en Apple Type Services (ATS) en Apple Mac OS X antes de v10.6.7 permite a atacantes remotos ejecutar código de su elección a través de un documento que contiene embebida una fuente de tipo 1.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mac OS X's CFF Decoder. 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 how the Type1Scaler library processes a specially formatted compact font file. When processing this file, the application will corrupt memory outside the bounds of an allocated buffer. This can lead to code execution under the context of the application that utilizes the library.
