Apple has shipped a high-priority QuickTime update to fix at least 14 security holes that expose computer users to hacker attacks.

The QuickTime 7.7 update, available for both Windows and Mac OS X, addresses flaws that could be exploited via rigged image, audio and movie files.

According to an advisory from Apple, some of the flaws could lead to remote code execution attacks if a user is tricked into clicking on a bobby-trapped web site or into opening a special media file.

Some of the more serious issues:

  • A buffer overflow existed in QuickTime's handling of pict files. Viewing a maliciously crafted pict file may lead to an unexpected application termination or arbitrary code execution. For Mac OS X v10.6 systems, this issue is addressed in Mac OS X v10.6.8. This issue does not affect Mac OS X v10.7 systems.
  • Multiple memory corruption issues existed in QuickTime's handling of JPEG2000 images. Viewing a maliciously crafted JPEG2000 image with QuickTime may lead to an unexpected application termination or arbitrary code execution. For Mac OS X v10.6 systems, this issue is addressed in Mac OS X v10.6.7. This issue does not affect Mac OS X v10.7 systems.
  • An integer overflow existed in QuickTime's handling of RIFF WAV files. Playing a maliciously crafted WAV file may lead to an unexpected application termination or arbitrary code execution. For Mac OS X v10.6 systems, this issue is addressed in Mac OS X v10.6.8. This issue does not affect Mac OS X v10.7 systems.
  • A memory corruption issue existed in QuickTime's handling of sample tables in QuickTime movie files. Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution. For Mac OS X v10.6 systems, this issue is addressed in Mac OS X v10.6.8. This issue does not affect Mac OS X v10.7 systems.
  • An integer overflow existed in QuickTime's handling of audio channels in movie files. Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution. For Mac OS X v10.6 systems, this issue is addressed in Mac OS X v10.6.8. This issue does not affect Mac OS X v10.7 systems.
  • A buffer overflow existed in QuickTime's handling of JPEG files. Viewing a maliciously crafted JPEG file may lead to an unexpected application termination or arbitrary code execution. For Mac OS X v10.6 systems, this issue is addressed in Mac OS X v10.6.8.
  • A heap buffer overflow existed in QuickTime's handling of GIF images. Viewing a maliciously crafted GIF image may lead to an unexpected application termination or arbitrary code execution. This issue does not affect Mac OS X systems.
  • Multiple stack buffer overflows existed in the handling of H.264 encoded movie files. Viewing a maliciously crafted H.264 movie file may lead to an unexpected application termination or arbitrary code execution. These issues do not affect Mac OS X systems.
  • A stack buffer overflow existed in the QuickTime ActiveX control's handling of QTL files. Visiting a maliciously crafted website using Internet Explorer may lead to an unexpected application termination or arbitrary code execution. This issue does not affect Mac OS X systems.
  • A heap buffer overflow existed in the handling of STSC atoms in QuickTime movie files. Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution. This issue does not affect Mac OS X v10.7 systems.
  • A heap buffer overflow existed in the handling of STSS atoms in QuickTime movie files. Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution. This issue does not affect Mac OS X v10.7 systems.
  • A heap buffer overflow existed in the handling of STSZ atoms in QuickTime movie files. Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution. This issue does not affect Mac OS X v10.7 systems.
  • A heap buffer overflow existed in the handling of STTS atoms in QuickTime movie files. Viewing a maliciously crafted movie file may lead to an unexpected application termination or arbitrary code execution. This issue does not affect Mac OS X v10.7 systems.
