Apple QuickTime sean Atom Size Parsing Remote Code Execution Vulnerability

CVE ID	CVE-2012-0670
CVSS SCORE	7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P
AFFECTED VENDORS	Apple
AFFECTED PRODUCTS	QuickTime
TREND MICRO CUSTOMER PROTECTION	Trend Micro TippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID ['12490']. For further product information on the TippingPoint IPS: http://www.tippingpoint.com
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 Quicktime.qts when parsing the 'sean' atom. The size specified in the atom's header is added to 0x0C and subsequently allocated. File data is then copied into that buffer along with a series of nulls. If the buffer is undersized, the copy operation can be made to corrupt adjacent memory. An attacker can leverage this vulnerability to execute code under the context of the process.
ADDITIONAL DETAILS	Apple has issued an update to correct this vulnerability. More details can be found at: http://support.apple.com/kb/HT5261
