Apple has released a security update to address the issue recently publicized by security firm Secunia. The vulnerability allows malicious scripts to be run just by getting someone to click a URL. The description of the update, which is called Security Update 2004-05-24, is sparse on details, merely saying that it updates HelpViewer, one of the weak links in the vulnerability.

To get it, go to Software Update under the Apple Menu.
