Description:
LMH has reported a vulnerability in Mac OS X, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the "do_hfs_truncate()" function when handling HFS+ file systems. This can be exploited via a DMG image containing a specially crafted HFS+ file system to cause a kernel panic.
NOTE: This is only remotely exploitable via the Safari web browser when the "opening safe files after downloading" option is enabled.
The vulnerability is reported in version 10.4.8 (x86). Other versions may also be affected.
Solution:
Update to Mac OS X 10.4.9 or install Security Update 2007-003.
