ZDI-10-258: Apple QuickTime 3GP Parsing Remote Code Execution Vulnerability

December 7, 2010

-- CVE ID:
CVE-2010-1508

-- CVSS:
10, (AV:N/AC:L/Au:N/C:C/I:C/A:C)

-- 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 Quicktime.qts module responsible for
parsing media files. While handling 3GP streams a function within this
module a loop trusts a value directly from the media file and uses it
during memory copy operations. By supplying a large enough value this
buffer can be overflowed leading to arbitrary code execution under the
context of the user accessing the file.

-- Vendor Response:
Apple has issued an update to correct this vulnerability. More
details can be found at:

http://support.apple.com/kb/HT4447
