Apple closes security gaps for QuickTime, iPhone, iPod Touch

Apple released the first patches for 2008 to the QuickTime media player as well as the iPhone and iPod Touch on January 15.

The updates to QuickTime 7.4 for Windows and Mac users are designed to prevent a system from being hijacked when malicious movie files are opened.

Apple Downloads lists the updates for Windows XP and Vista as well as Mac OS X 10.3.9 and higher. Mac users also can access the download via Apple’s Software Update.

Memory corruption issues in QuickTime’s handling of Sorenson 3 video, Macintosh Resource Records, and Image Descriptor atoms are to blame for three of four noted security holes. The fix also closes a gap left when QuickTime processes compressed PICT graphics. Read more »

ATI Radeon HD 3870 X2 card goes official

AMD’s ATI Radeon HD 3870 X2 uses two 3D chips to process game graphics.

A week after it was supposed to, AMD announced its Radeon HD 3870 X2 graphics card today. Roughly $450 will get you this high-end 3D card, which melds two Radeon HD 3870 chips onto a single 3D card package. The resulting performance is basically the same as two standalone Radeon HD 3870 cards in AMD’s multicard ATI Crossfire mode. Various review sites show it competing more or less well against Nvidia’s GeForce 8800 GTX and 8800 Ultra cards, although neither AMD nor Nvidia can claim an across-the-board victory.

Our illustrious colleagues at GameSpot are working dilligently on updating their benchmarks for this card after a late-breaking driver update (the reason for the cancellation of last Monday’s announcement). We weren’t originally going to retest, but for reasons unrelated to the driver, we decided we would. Once we have scores, both CNET and Gamespot will post our respective reviews. In the meantime, Anandtech, ExtremeTech, and PC Perspective have well-done coverage of AMD’s new card. And how do those sites find the DirectX 10 performance picture?

It depends on your definition of an acceptable frame rate. On the DX10 version of Company of Heroes, for example, Anandtech shows all cards in this high-end neighborhood performing well. The DX10 implementation in that game is minor, though. In Crysis, the posterchild for next-gen gaming, neither AMD nor Nvidia can muster an average of even 30 frames per second at even a forgiving 1,280 x 1,024. Where we come from, it’s 60 frames or nothing for first person shooters like Crysis. So either Crysis is ahead of its time, or the graphics card vendors have been too slow to adjust. Either way, it’s frustrating for gamers that even their multi-thousand dollar rigs will still likely choke on a game that’s been out for three months

Yahoo Messenger for Vista preview available

Yahoo is set to release a preview of Yahoo Messenger for Vista on Thursday.

It’s just a preview, or a very early version, so it doesn’t have all the features other versions of Yahoo Messenger do, such as voice, Webcam, chat rooms, text messaging to mobile phones, easy photo sharing and conferencing. Those features will come later.

What it does have is a new interface, and it lets you organize conversations into tabs and drag and drop tabs out to create a new window. You can also keep favorite contacts by dragging them into the Windows Sidebar gadget, send enhanced emoticons, change the color of IM windows, adjust the display size of the contacts, arrange your contact list into multiple columns, and send files as large as 2 gigabytes.

“We know it’s been a long wait for Yahoo Messenger for Vista and we can’t thank you enough for your patience,” says Josh Jacobson, senior product manager for Yahoo Messenger for Vista.
