					This module can be used to execute arbitrary code on IIS servers
					that expose the /msadc/msadcs.dll Microsoft Data Access Components
					(MDAC) Remote Data Service (RDS) DataFactory service. The service is
					exploitable even when RDS is configured to deny remote connections
					(handsafe.reg). The service is vulnerable to a heap overflow where
					the RDS DataStub 'Content-Type' string is overly long. Microsoft Data
					Access Components (MDAC) 2.1 through 2.6 are known to be vulnerable.
