Safari

CVE-ID: CVE-2007-2398

Available for: Windows XP or Vista

Impact: A maliciously crafted website may control the contents of the address bar.

Description: A timing issue in Safari 3.1 allows a web page to change the contents of the address bar without loading the contents of the corresponding page. This could be used to spoof the contents of a legitimate site, allowing user credentials or other information to be gathered. This issue was addressed in Safari Beta 3.0.2, but reintroduced in Safari 3.1. This update addresses the issue by restoring the address bar contents if a request for a new web page is terminated. This issue does not affect Mac OS X systems.
