-- 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 in the parsing of PICT files in QuickTime.qts.
While processing data for opcode 0x71 QuickTime trusts a value contained
in the file and makes an allocation accordingly. By providing a
malicious value this buffer can be undersized and subsequently can be
overflowed leading to arbitrary code execution under the context of the
user running QuickTime.

-- Vendor Response:
Apple has issued an update to correct this vulnerability. More
