Apple Mac OS X SMB Utilities Local Stack-Based Buffer Overflow Vulnerability

Mac OS X is prone to a local stack-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.

This issue affects certain SMB (Server Message Block protocol) applications.

An attacker can exploit this issue to execute arbitrary code with superuser privileges. Successful attacks will completely compromise affected computers. Failed exploit attempts will result in a denial of service.

Mac OS X and Mac OS X Server 10.4.11 and prior versions are vulnerable.

NOTE: This issue was originally covered in BID 26910 (Apple Mac OS X v10.5.1 2007-009 Multiple Security Vulnerabilities).
