EMC AutoStart ftAgent Opcode 85 Subcode 01 Parsing Remote Code Execution Vulnerability

CVE ID	CVE-2012-0409
CVSS SCORE	10.0, AV:N/AC:L/Au:N/C:C/I:C/A:C
AFFECTED VENDORS	EMC
AFFECTED PRODUCTS	AutoStart
TREND MICRO CUSTOMER PROTECTION	Trend Micro TippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID ['12435']. 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 EMC Autostart. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ftAgent.exe service, which listens by default on TCP port 8045. When handling messages with opcode 85 (0x55) and subcode 01, the process performs arithmetic on an unvalidated user-supplied value used to determine the size of a new heap buffer, allowing a potential integer wrap to cause a heap buffer overflow. This vulnerability can be leveraged to execute code under the context of the SYSTEM user.
ADDITIONAL DETAILS	EMC has issued an update to correct this vulnerability. More details can be found at: http://www.securityfocus.com/archive/1/522835/30/0/threaded
