Apple Quicktime Dataref URI Buffer Remote Code Execution Vulnerability

CVE ID	CVE-2011-3459
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 ['12408']. 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 QuickTime Player. 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 occurs when parsing a movie file containing multiple atoms with a different string length. When resizing a buffer in order to make space for the string, the application will forget to include the null-terminator. When the application attempts to null-terminate the string, an out-of-bounds write will occur. If an aggressor can place the a useful heap buffer contiguous to the reallocated string, this can lead to code execution under the context of the applicaiton.
ADDITIONAL DETAILS	Apple has issued an update to correct this vulnerability. More details can be found at: http://support.apple.com/kb/HT5130
