Safari 4.02, for Mac and Windows, was released yesterday to address a couple of serious security issues. Both vulnerabilities can be triggered by visiting a maliciously crafted website and could result in arbitrary code execution or a cross-site scripting attack. Also included in version 4.02 are stability improvements to the browser's JavaScript engine.

About's Tom Nelson has further details on the release. It is recommended that Safari users upgrade their browsers immediately.

The majority of iPhone and iPod touch users surf the Web using their device's default browser, Safari. Although Apple's browser is a respectable offering, there are several other options available for download via the App Store. Most people are unaware of this fact, assuming that Safari is the only way to go. These Safari alternatives each have their own unique pros and cons.

As we head into the holiday weekend, it's time to profile another browser for the iPhone and iPod touch. Thursday's entry into the fray is the Magic Browser, a mobile application that does a lot to live up to its name.

Boasting a number of extremely useful features not found in most competitors, including the ability to save Web pages in several different formats for offline viewing and single touch tabbed browsing, Magic Browser goes the extra mile.

However, the price is significantly higher than most other iPhone and iPod touch browsers. Available via the App Store for $4.99, Magic Browser is the type of application that is only worth it if its unique features are things that you would use regularly.
