Description

Microsoft Visual Basic Hierarchical FlexGrid ActiveX is prone to overflow conditions. The ActiveX control fails to properly sanitize user-supplied input passed to the "Rows" and "Cols" properties as well as "ExpandAll()" and "CollapseAll()" methods resulting in integer overflows. With a specially crafted web page, a remote attacker can corrupt memory.
