Heap-based buffer overflow in the MaskedEdit ActiveX control in Msmask32.ocx 6.0.81.69, and possibly other versions before 6.0.84.18, in Microsoft Visual Studio 6.0, Visual Basic 6.0, Visual Studio .NET 2002 SP1 and 2003 SP1, and Visual FoxPro 8.0 SP1 and 9.0 SP1 and SP2 allows remote attackers to execute arbitrary code via a long Mask parameter, related to not "validating property values with boundary checks," as exploited in the wild in August 2008, aka "Masked Edit Control Memory Corruption Vulnerability."

Buffer overflow in Microsoft Visual Basic 6.0 and Enterprise Edition 6.0 SP6 allows user-assisted remote attackers to execute arbitrary code via a Visual Basic project (vbp) file containing a long Reference line, related to VBP_Open and OLE. NOTE: there are limited usage scenarios under which this would be a vulnerability.

Object linking and embedding (OLE) Automation, as used in Microsoft Windows 2000 SP4, XP SP2, Server 2003 SP1 and SP2, Office 2004 for Mac, and Visual Basic 6.0 allows remote attackers to execute arbitrary code via the substringData method on a TextNode object, which causes an integer overflow that leads to a buffer overflow.

Multiple stack-based buffer overflows in Microsoft Visual Basic 6 allow user-assisted remote attackers to cause a denial of service (CPU consumption) or execute arbitrary code via a Visual Basic Project (vbp) file with a long (1) Description or (2) Company Name (VersionCompanyName) field.

Unspecified vulnerability in Microsoft Visual Basic (VB) 6 has an unknown impact ("overflow") via a project that contains a certain Click event procedure, as demonstrated using the msgbox function and the VB.Label object.
