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.

ADDITIONAL DETAILS Apple has issued an update to correct this vulnerability. More details can be found at:
