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 03 and subcode 04, 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:
