Apple slams shut TEN code execution holes in QuickTime on Windows

Apple has patched security vulnerabilities in the Windows version of its QuickTime media player that allowed malicious video files to execute arbitrary code.

The entertainment goliath said version 7.7.5 of QuickTime will fix 10 serious bugs that can be exploited to crash the software or pull off remote-code execution on Windows 7, Vista and XP PCs. The holes were reported by researchers at Microsoft, iDefense VCP, Tencent Security Team and others through HP's Zero Day Initiative.

According to Apple, the bugs are:

    An uninitialized pointer issue existed in the handling of track lists.
    A buffer overflow existed in the handling of H.264 encoded movie files.
    An out of bounds byte swapping issue existed in the handling of QuickTime image descriptions.
    A signedness issue existed in the handling of 'stsz' atoms.
    A buffer overflow existed in the handling of 'ftab' atoms.
    A memory corruption issue existed in the handling of 'dref' atoms.
    A buffer overflow existed in the handling of 'ldat' atoms.
    A buffer overflow existed in the handling of PSD images.
    An out of bounds byte swapping issue existed in the handling of 'ttfo' elements.
    A buffer overflow existed in the handling of 'clef' atoms.

Malware could end up on a vulnerable machine if the user visits a drive-by-download website that hosts a specially crafted movie; the QT player would open the file, triggering a bug and executing code to install software nasties.

The updates can be obtained through the Apple Software Update tool or from the company's security downloads page. Apple did not report any attacks in the wild targeting the flaws.
