Apple Mac OS X 10.6.2 Update Breaks Intel Atom CPU Support

Written By Sam on 11 November 2009

Earlier today we wrote about Mac OS X v10.6.2 Update which fixes several bugs and has also got many improvements. Along with these, Apple also fixed some more serious issues in the Security Update 2009-006/Mac OS X v10.6.2 patch bundle.

AFP Client – Multiple memory corruption issues which occur upon connecting to a malicious AFP server have been rectified in the updated version of Mac OS X10.6.2.

Apache – Apache updated to version 2.2.13 inorder to address several vulnerabilities including the most serious one’s leading to privilege escalation. A separate patch corrects flaw, which allows an attacker to use the TRACE HTTP method in the Apache Web server thus enabling cross-site scripting attacks through certain web client software.

Apache Portable Runtime – Multiple integer overflows which may lead to an unexpected application termination or arbitrary code execution in Apache Portable Runtime (APR) has been fixed.

CoreGraphics and CoreMedia – Multiple integer overflows in CoreGraphics’ handling of PDF files and memory corruption issues in handling of H.264 movie files which may result in a heap buffer overflow which may lead to an unexpected application termination or arbitrary code execution.

Dictionary and DirectoryService – A design issue in Dictionary that may allow another user on the local network to execute arbitrary code on the user’s system and memory corruption issue exists in DirectoryService have been resolved.

Disk Images and ImageIO – Heap buffer overflow existing in the handling of disk images containing FAT filesystems and a buffer underflow existing in ImageIO’s handling of TIFF images which may cause unexpected application termination or arbitrary code execution have been taken care of in the updated version.

Kernel – Multiple input validation issues existing in Kernel’s handling of task state segments that may allow a local user to cause information disclosure, an unexpected system shutdown, or arbitrary code execution has been resolved in the current version.

Dovecot Sieve – multiple buffer overflows which occur after implementing a maliciously crafted dovecot-sieve script has been resolved in the second version of Mac OS X10.6.2.


Seems that Apple’s final Mac OS X 10.6.2 update is not working with Intel’s Atom processors. Atom chipsets have been a common factor with a variety of Mac-clone netbooks and this move by Apple can be an obstacle for users attempting to configure ‘Hackintosh‘ systems. Experts recommend the consumers using OS X on Atom-based systems not to install this second update of Mac OS X10.6.2.
