Alongside Mac OS X 10.7.4 and to address roughly the same set of vulnerabilities, Apple has released Security Update 2012-002 for Snow Leopard and Snow Leopard Server. The fixes revolve around the open source components of Mac OS X (including curl, Ruby, and Samba), directory services, and dealing with maliciously crafted files in ImageIO, QuickTime, and various other internal libraries. Unlike some other recent Apple updates, we haven’t seen any widespread reports of problems. (Free, 238.73/258.11 MB)
Copy Disk Image as Folder
When you open a .dmg file, a disk image is mounted. You are then generally supposed to copy the contents of that disk image to your hard drive (to your Desktop, your Applications folder, or wherever). But what if you want to copy the whole disk image, including all its contents, as a folder? Hold the Option key, and drag the "proxy icon" in the title bar of the disk image window to the destination in the Finder.

I recall reading somewhere (probably TidBITS) Apple staggers their software update notifications to keep their servers from being overwhelmed.
