Apple has released Security Update 2010-003 (Leopard-Client) to address a critical vulnerability in the way Apple Type Services in Mac OS X 10.6 Snow Leopard parses embedded fonts. Users who view or download any documents containing maliciously crafted embedded fonts run a risk of arbitrary code execution. The update addresses this issue by improving index checking. This vulnerability was first demonstrated by Charlie Miller at the Pwn2Own conference 20 days ago, which shows a reasonably quick response on Apple's part. A nearly identical update - Security Update 2010-003 (Leopard-Server) - that eliminates the same vulnerability is available for Leopard Server. The update requires you are running Mac OS X 10.5.8 and is available via Software Update and the Apple Support Downloads page. (Free, 218.6/379.5 MB)
Adjust Multiple Column Sizes Simultaneously
Within the Finder, Column View enables you to see folder hierarchies, with each subsequent level getting its own column. Dragging on the double lines at the base of a column divider changes the preceding column's width. But Option-drag on any divider, and all the columns in the window change to the same width.
