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."

(There is total information disclosure, resulting in all system files being revealed.)
(There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being compromised.)
(There is a total shutdown of the affected resource. The attacker can render the resource completely unavailable.)
(The access conditions are somewhat specialized. Some preconditions must be satistified to exploit)
(The vulnerability requires an attacker to be logged into the system (such as at a command line or via a desktop session or web interface).)
