The monthly security update includes a patch to prevent phishing attacks via Apple’s Safari browser.
This vulnerability is caused by the browser’s support for the Internationalized Domain Name (IDN) protocol, which is designed to make it easier for users to jump from one international website to another by allowing the browser to easily recognise foreign characters.
Phishing scammers have used the protocol to trick users into thinking they are viewing a trusted site when they are not.
Apple says it has closed this security hole with the Safari patch, following the likes of Mozilla and Opera, which have done the same with their patches.
Microsoft’s Internet Explorer does not support IDN so is not affected by the vulnerability.
