Apple posts QuickTime security fix

Apple has issued a new release of QuickTime, patching critical security issues with the media playing software.

Apple has released an update to its QuickTime media player, fixing a number of critical security bugs in the software.

The QuickTime 7.3 update, released yesterday, fixes seven bugs in the software. Six of the flaws could allow an attacker to run unauthorized software on a victim's PC. To do this, the attacker would first need to trick the victim into viewing a maliciously crafted movie or image file, Apple said.

The seventh flaw lies in QuickTime for Java, and it could be used to gain access to sensitive information or to run Java applets with elevated privileges, Apple said. The QuickTime patches issued Monday are for the latest versions of the Mac OS X operating system as well as Windows Vista and XP.

None of the bugs had been previously disclosed to the public, said Andrew Storms, director of security operations with nCircle Network Security, via instant message.

In the past year, QuickTime has been closely scrutinized by security researchers, and this latest update was Apple's fifth QuickTime security fix for the year. The previous update, QuickTime 7.2, released in July, featured eight bug-fixes.

Apple credited outside researchers from companies like Adobe, Verisign and 3Com for reporting the bugs it patched.

"QuickTime seems to have become a new flavor of the month for researchers," Storms said. "I think part of the reason for the attention is that its cross platform. Many of the attacks will work on both Windows and Mac, and with Apple's market share in the PC market growing, there won't be any let-down to the attention that the hackers are giving Apple."

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
