Apple on Wednesday released an update to its Safari Web browser for Mac OS X and Windows. The new release is available for download from Apple's Web site and through the Software Update system preference.

Apple indicates in its release note that Safari 3.1.1 "includes improvements to stability, compatibility and security," though the company did not offer any further clarification in that note. Apple recommends the update for all Safari users.

In a separately published tech note, Apple offered more details about what Safari 3.1.1 fixes in terms of security. Issues that affect the Mac version of Safari include a change to WebKit to improve handling of URLs to prevent cross-site scripting, and additional validation of JavaScript regular expressions to help prevent a heap buffer overflow that can cause Safari to unexpectedly quit or execute code.
