ZDI-11-304 : Apple Quicktime Advanced Audio Codec Frame Parsing Remote
Code Execution Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-11-304
October 26, 2011

-- CVE ID:
CVE-2011-3252

-- CVSS:
8.3, AV:N/AC:M/Au:N/C:P/I:P/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 Player. Authentication is
not required to exploit this vulnerability. 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 an audio
stream encoded with the advanced audio codec. A field will be read from
the file in order to calculate a length that is later used in a memory
copy operation into a statically sized buffer. Successful exploitation
can lead to code execution under the context of the application.

-- Vendor Response:

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