Multiple integer overflows in the Hierarchical FlexGrid ActiveX control (mshflxgd.ocx) in Microsoft Visual Basic 6.0 and Visual FoxPro 8.0 SP1 and 9.0 SP1 and SP2 allow remote attackers to execute arbitrary code via crafted (1) Rows and (2) Cols properties to the (a) ExpandAll and (b) CollapseAll methods, related to access of incorrectly initialized objects and corruption of the “system state,” aka “Hierarchical FlexGrid Control Memory Corruption Vulnerability.”

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.”

The DataGrid ActiveX control in Microsoft Visual Basic 6.0 and Visual FoxPro 8.0 SP1 and 9.0 SP1 and SP2 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 “DataGrid Control Memory Corruption Vulnerability.”

The Server service in Microsoft Windows 2000 SP4, XP SP2 and SP3, Server 2003 SP1 and SP2, Vista Gold and SP1, Server 2008, and 7 Pre-Beta allows remote attackers to execute arbitrary code via a crafted RPC request that triggers the overflow during path canonicalization, as exploited in the wild by Gimmiv.A in October 2008, aka “Server Service Vulnerability.”
