Secunia Research has discovered some vulnerabilities in Microsoft Hierarchical FlexGrid Control bundled with various products, which can be exploited by malicious people to compromise a user’s system. The vulnerabilities are caused due to integer overflow errors in the ActiveX control (mshflxgd.ocx) when handling the “Rows” and “Cols” properties and the “ExpandAll()” and “CollapseAll()” methods. These can be exploited to corrupt memory. Successful exploitation allows execution of arbitrary code. Microsoft Hierarchical FlexGrid Control 6.0.88.4 is affected.
