Apple's disappearing Rapid Security Response update
Apple on Monday distributed its latest Rapid Security Response update to iPhones, iPads, and Macs, rolling out an important security patch to protect devices against a recently identified attack Apple says is already in active use.
“Apple is aware of a report that this issue may have been actively exploited,” the company said in its security note.
That’s bad, as it means someone somewhere has already been attacked using this vulnerability. The patch repairs a flaw found in WebKit in which processing web content could lead to arbitrary code execution.
