-- 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 how the application parses
directBitsRect records within a .pict file. When decompressing data
within this structure, the application will allocate space for the
target buffer using fields described within the file and then use a
different length to decompress the total data from the file. This can
lead to code execution under the context of the application.

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