A buffer overflow vulnerability exists in a component of Apple's Mac OS X operating system that handles Microsoft Word files.
The Cocoa Application Framework (also referred to as the Application Kit, or AppKit) is one of the core Cocoa frameworks supplied with Apple's Mac OS X operating system. It provides functionality and associated Application Program Interfaces (APIs) for applications, including objects for graphical user interfaces (GUIs), event-handling mechanisms, application services, and drawing and image composition facilities.
A buffer overflow exists in the AppKit component designed to handle Microsoft Word (.doc) files. Apple notes in its security advisory that this vulnerability only affects applications that use AppKit (such as TextEdit) and that Microsoft Word for Mac OS X is not vulnerable. A maliciously crafted .doc file could be used to execute arbitrary code on a vulnerable system.
An attacker with the ability to supply a maliciously crafted Microsoft Word .doc file could execute arbitrary code on a vulnerable system. The attacker-supplied code would be executed with the privileges of the user opening the malicious file.
