EMC AutoStart ftAgent Opcode 0x2d Subcode 0x1194 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 the EMC Autostart ftAgent, which is deployed on machines managed by EMC Autostart by default. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing routines for op-codes used by EMC Autostart ftAgent's proprietary network protocol. This ftAgent.exe service listens on TCP port 8045, and performs arithmetic for memory size calculation using values read from the network without validation. This arithmetic is susceptible to integer overflow, causing the memory allocation to be undersized, ultimately allowing for heap-based memory corruption. An attacker can exploit this condition to gain remote code execution as user SYSTEM.
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
