The Microsoft Access Wizard Controls in ACCWIZ.dll in Microsoft Office Access 2003 SP3 and 2007 SP1 and SP2 do not properly interact with the memory-allocation approach used by Internet Explorer during instantiation, which allows remote attackers to execute arbitrary code via a web site that references multiple ActiveX controls, as demonstrated by the ImexGrid and FieldList controls, aka "Access ActiveX Control Vulnerability."

The FieldList ActiveX control in the Microsoft Access Wizard Controls in ACCWIZ.dll in Microsoft Office Access 2003 SP3 does not properly interact with the memory-access approach used by Internet Explorer and Office during instantiation, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via an HTML document that references this control along with crafted persistent storage data, aka "ACCWIZ.dll Uninitialized Variable Vulnerability."
