A vulnerability has been reported in Mac OS X, which can be exploited by malicious, local users to gain escalated privileges.
The problem is that permissions in BOM files are not properly validated and can be exploited to create new permissions on specified files and directories, or gain root privileges by creating a specially crafted BOM file and then running "diskutil repairPermissions /".
The vulnerability is reported in version 10.4.8 . Other versions may also be affected.
Solution: Remove the setuid bit from /System/Library/PrivateFrameworks/DiskManagement.framework/Resources/DiskManagementTool.
Provided and/or discovered by: Discovered as a 0-day and reported by LMH and Kevin Finisterre (MOAB).
