TippingPoint™ IPS Customer ProtectionTippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID 12435. For further product information on the TippingPoint IPS:
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 50 (0x32) and subcode 02, 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.
