More Security Updates for Mac OS X

For the second time in a month, Apple has released a bundle of software security patches for its Mac OS X and Mac OS X Server operating systems.

The fixes, also detailed in a write-up from Danish security company Secunia, plug 20 separate security holes. Secunia rated most of the vulnerabilities "highly critical," which means that while the bad guys could use the flaws to take control of vulnerable computers, security experts don't have any evidence that attackers have done so yet.

The patches fix problems in many areas of Apple's operating systems, ranging from Apache -- the Web server built into Mac OS X -- to several glitches in the Mac version of Bluetooth, a communication service that lets otherwise dissimilar wireless devices exchange information over short distances.

You can get the updates from the "Apple Downloads" page and install them yourself, or you can let Apple's software update service handle them for you.

And if you missed the patches Apple released last month, here's my write-up.
