Just before researchers were to discuss the Safari browser's security flaws (as exhibited on desktops as well as on iPhones) at the BlackHat conference, Apple put out a big patch late Tuesday to fix more than four dozen holes. This includes five known vulnerabilities in the iPhone, including those that, as Apple puts it, allowed Web sites to cause "arbitrary code execution" on the phone.
In other words when you download the patch -- it'll transfer to your iPhone through iTunes -- your phone should no longer be vulnerable to the hole that Avi Rubin and his team at Independent Security Evaluators found could let attackers gain full access to the device.
Other security fixes put out by Apple address problems in, among other Mac subsystems, iChat, the WebCore and WebKit application frameworks, and the CoreAudio sound API. Update your Mac today.
