Send Article to a Friend

Apple has released Security Update 2013-003 for OS X 10.8 Mountain Lion (20.4 MB) as well as for 10.7 Lion and 10.6 Snow Leopard, both of which receive two versions: Lion (61 MB) and Lion Server (111.3 MB), plus Snow Leopard (349.5 MB) and Snow Leopard Server (424.5 MB). All versions of this security update close vulnerabilities with buffer overflows within QuickTime that could lead to “unexpected application termination or arbitrary code execution.” In particular, the updates deal with buffer overflows in Sorenson and H.264 encoded movie files, plus the handling of “mvhd” movie header atoms.

Installed this last night on my 10.6 MacBook. Fried my system...I can boot from Carbon Copy Cloner clone on external HD, but can't boot from my internal HD (actually, an SSD). I guess it's time to reformat my SSD and restore, huh? (Yes, I've tried TechTool, DiskUtility, etc...Applejack says it's waiting for root device.)
Anyone else having this issue?
