iTunes Cover Flaw

A bug in the way iTunes processes album cover art could leave you exposed to a criminal who could completely hijack your PC. You'd first have to click on a tainted music file, and no attack code for this hole has surfaced yet, but fixing iTunes is still a good idea. Downloading version 7.4 or higher will protect you.

Excel's 65535 Problem

Good news: If your salary is exactly $65,535 and your company handles its payroll in Excel 2007, you may be in for a big raise! Microsoft acknowledged that in certain specific circumstances, if a calculation yields the answer 65,535, the number displayed will be 100,000. The key word in that description is "displayed"--Microsoft says that behind the scenes Excel knows the real answer, but the program shows the wrong figure. You can find more information and the patch at the Microsoft Excel team blog.
