SYMPTOMS

When you are using Microsoft Commercial Internet System version 1.0 Microsoft Personalization System, an Active Server Page (ASP) file calls sendmail and is handled by a VBScript. The VBScript calls the Sendmail.dll file that is passing an invalid Nullpointer and crashing the sendmail component. The error occurs with Smail.dll version 4.72.2106.1. Access violations occur from every 30 minutes to 24 hours before failure occurs.

CAUSE

The problem results from CSSODispatch::Invoke passing a Null parameter as pvarResult, and SSOSendMail not checking for NULL before use.
