ZDI-12-136 : Apple QuickTime Invalid Public Movie Atom Remote Code Execution Vulnerability http://www.zerodayinitiative.com/advisories/ZDI-12-136 August 17, 2012

  • -- CVE ID: CVE-2011-3220

  • -- CVSS: 7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P

  • -- Affected Vendors: Apple

  • -- Affected Products: Apple QuickTime

  • -- Vulnerability Details: This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Apple's QuickTime player. User interaction is required to exploit this vulnerability in that the target must visit a malicious page.

The specific flaw exists within how the application handles a malformed atom type when playing a movie encoded with uncompressed audio. When decoding the audio sample the application will use a 16-bit length for allocating a buffer, and a different one for initializing it. This can cause memory corruption which 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: http://support.apple.com/kb/HT1222
