Apple Mac OS X AppleTalk AIOCRegLocalZN IOCTL Stack Buffer Overflow Vulnerability

Apple Mac OS X AppleTalk AIOCRegLocalZN IOCTL Stack Buffer Overflow Vulnerability

Apple Mac OS X is prone to a local memory-corruption vulnerability. This issue occurs when the operating system fails to handle specially crafted arguments to an IOCTL call.

Due to the nature of this issue, an attacker may be able to execute arbitrary machine code in the context of the affected kernel, but this has not been confirmed. Failed exploit attempts result in kernel panics, denying service to legitimate users.

Mac OS X version 10.4.8 is vulnerable to this issue; other versions may also be affected.
