GE Proficy Historian ihDataArchiver.exe Trusted Header Size Remote Code Execution Vulnerability

CVE ID	CVE-2011-1918
CVSS SCORE	10.0, AV:N/AC:L/Au:N/C:C/I:C/A:C
AFFECTED VENDORS	GE

TREND MICRO CUSTOMER PROTECTION	Trend Micro TippingPoint IPS customers are protected against this vulnerability by Digital Vaccine protection filter ID ['11646']. 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 GE Proficy Historian. Authentication is not required to exploit this vulnerability. The specific flaw exists within the ihDataArchiver.exe process which listens by default on TCP port 14000. The code within this module trusts a value supplied over the network and uses it as a length when copying user-supplied data to a stack buffer. By providing a large enough value, this buffer can be overflowed leading to arbitrary code execution under the context of the user running the service.
ADDITIONAL DETAILS	GE has issued an update to correct this vulnerability. More details can be found at: http://support.ge-ip.com/support/index?page=kbchannel&id=S:KB14493
