Microsoft warned on Friday that Apple's Safari Web browser for Windows exposes PCs to a security hole that permits potentially malicious files to be downloaded to a user's machine and run without prompting the user.
Microsoft's advisory comes two weeks after security researcher Nitesh Dhanjani warned both Redmond and Cupertino that Safari introduces a vulnerability in Windows and OS X machines, which allows any rogue Web site to "carpet bomb" the user's Desktop (Windows), or Downloads directory (Apple), with unwanted files (Safari is not installed by default on Windows machines).
