Apple Addresses Security Issue in Safari 3.1.2 for Windows
Computerworld reports that the new version of Safari for Windows provides a fix for a possible "carpet bomb" issue that was described by Nitesh Dhanjani in May. This exploit alone was considered a nuisance by itself, but combined with other flaws in Windows and Internet Explorer could have resulted in a security risk.
This latest update appears to address this and other security issues for Safari for Windows users.
