The FlexGrid ActiveX control in Microsoft Visual Basic 6.0, Visual FoxPro 8.0 SP1 and 9.0 SP1 and SP2, Office FrontPage 2002 SP3, and Office Project 2003 SP3 does not properly handle errors during access to incorrectly initialized objects, which allows remote attackers to execute arbitrary code via a crafted HTML document, related to corruption of the "system state," aka "FlexGrid Control Memory Corruption Vulnerability."
