Adobe Shockwave NPAPI Plug-in Drag and Drop Remote Code Execution Vulnerability

CVE ID	CVE-2011-2127
CVSS SCORE	8.3, AV:N/AC:M/Au:N/C:C/I:P/A:P
AFFECTED VENDORS	Adobe
AFFECTED PRODUCTS	Shockwave Player
TREND MICRO CUSTOMER PROTECTION	Trend Micro TippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID ['11298']. 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 the NPAPI version of the Adobe Shockwave 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 exists within how the application manages a reference to a COM object. Upon destruction of the tab containing the plugin, the application will disable Drag and Drop functionality utilizing a method within the ole32 shared library. This will cause the application to attempt to destroy the object a second time. Under controlled circumstances, this can grant an attacker the ability to execute remote code under the context of the application.
ADDITIONAL DETAILS	Adobe has issued an update to correct this vulnerability. More details can be found at: http://www.adobe.com/support/security/bulletins/apsb11-17.html
