Apple has released Safari 7.0.4 for users of OS X 10.9 Mavericks and Safari 6.1.4 for users of 10.8 Mountain Lion and 10.7 Lion, both of which fix multiple critical vulnerabilities associated with WebKit. According to the security note for these updates, both versions of Safari fix a swath of memory corruption issues within the rendering engine that could lead to arbitrary code execution after visiting a maliciously crafted Web site. They also deal with a problem with handling Unicode characters in URLs that could enable a maliciously crafted URL to send out an incorrect postMessage origin. Both updates are available only through Software Update. (Free, 10.9+/10.7–10.8)
Editing iCal Events in Snow Leopard
Snow Leopard makes looking at event details in iCal easier. In the Leopard version of iCal, you had to double-click an event to reveal only some information in a pop-up box; you then needed to click the Edit button (or press Command-E) to edit an item's information. In Snow Leopard, choose Edit > Show Inspector (or press Command-Option-I) to bring up a floating inspector that provides an editable view of any items selected in your calendar.
