msdia.dll in Microsoft Debug Interface Access (DIA) SDK, as distributed in Microsoft Visual Studio before 2013, does not properly validate an unspecified variable before use in calculating a dynamic-call address, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted PDB file.

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."

Absolute directory traversal vulnerability in a certain ActiveX control in the VB To VSI Support Library (VBTOVSI.DLL) 1.0.0.0 in Microsoft Visual Studio 6.0 allows remote attackers to create or overwrite arbitrary files via a full pathname in the argument to the SaveAs method. NOTE: contents can be copied from local files via the Load method.

A certain ActiveX control in PDWizard.ocx 6.0.0.9782 and earlier in Microsoft Visual Studio 6.0 exposes dangerous (1) StartProcess, (2) SyncShell, (3) SaveAs, (4) CABDefaultURL, (5) CABFileName, and (6) CABRunFile methods, which allows remote attackers to execute arbitrary programs and have other impacts, as demonstrated using absolute pathnames in arguments to StartProcess and SyncShell.

Stack-based buffer overflow in a certain ActiveX control in VDT70.DLL in Microsoft Visual Database Tools Database Designer 7.0 for Microsoft Visual Studio 6 allows remote attackers to execute arbitrary code via a long argument to the NotSafe method. NOTE: this may overlap CVE-2007-2885 or CVE-2005-2127.

Microsoft Visual Studio 6.0 allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code by instantiating certain Visual Studio 6.0 ActiveX COM Objects in Internet Explorer, including (1) tcprops.dll, (2) fp30wec.dll, (3) mdt2db.dll, (4) mdt2qd.dll, and (5) vi30aut.dll.

Stack-based buffer overflow in Microsoft Visual Studio 6.0 and Microsoft Visual InterDev 6.0 allows user-assisted attackers to execute arbitrary code via a long DataProject field in a (1) Visual Studio Database Project File (.dbp) or (2) Visual Studio Solution (.sln).

The Microsoft virtual machine (VM) in Internet Explorer 4.x and 5.x allows a remote attacker to read files via a malicious Java applet that escapes the Java sandbox, aka the "VM File Reading" vulnerability.
