ZDI-12-079 : Apple QuickTime H264 Picture Width Parsing Remote Code
Execution Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-12-079
June 6, 2012

• – CVE ID:
  CVE-2012-0665

• – CVSS:
  7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P

• – Affected Vendors:

Apple

• – Affected Products:

Apple QuickTime

• – Vulnerability Details:
  This vulnerability allows remote attackers to execute arbitrary code on
  vulnerable installations of Apple QuickTime. User interaction is required
  to exploit this vulnerability in that the target must visit a malicious
  page or open a malicious file.

The specific flaw exists within the QuicktimeH264 modules in the QuickTime
player that handles H264 encoded movies. When the value for
'pic_width_in_mbs_minus_1' and 'pic_height_in_map_units_minus_1' in the
AVCC header data differs from the actual picture width and height a heap
buffer overflow occurs. This can result in remote code execution under the
context of the current process.

• – Vendor Response:

Apple has issued an update to correct this vulnerability. More details can
