Unspecified vulnerability in Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via unspecified vectors involving memory corruption from an unhandled error.

Microsoft Internet Explorer 4.0 through 7 allows remote attackers to determine the existence of local files that have associated images via a res:// URI in the src property of a JavaScript Image object, as demonstrated by the URI for a bitmap image resource within a (1) .exe or (2) .dll file.

Stack-based buffer overflow in certain ActiveX controls in (1) FPOLE.OCX 6.0.8450.0 and (2) Foxtlib.ocx, as used in the Microsoft Visual FoxPro 6.0 fpole 1.0 Type Library; and Internet Explorer 5.01, 6 SP1 and SP2, and 7; allows remote attackers to execute arbitrary code via a long first argument to the FoxDoCmd function.

Integer underflow in the CDownloadSink class code in the Vector Markup Language (VML) component (VGX.DLL), as used in Internet Explorer 5.01, 6, and 7 allows remote attackers to execute arbitrary code via compressed content with an invalid buffer size, which triggers a heap-based buffer overflow.

Unspecified vulnerability in Internet Explorer 5.01 and 6 SP1 allows remote attackers to execute arbitrary code via crafted Cascading Style Sheets (CSS) strings that trigger memory corruption during parsing, related to use of out-of-bounds pointers.

The tblinf32.dll (aka vstlbinf.dll) ActiveX control for Internet Explorer 5.01, 6 SP1, and 7 uses an incorrect IObjectsafety implementation, which allows remote attackers to execute arbitrary code by requesting the HelpString property, involving a crafted DLL file argument to the TypeLibInfoFromFile function, which overwrites the HelpStringDll property to call the DLLGetDocumentation function in another DLL file, aka "ActiveX Object Vulnerability."

Unspecified vulnerability in the pdwizard.ocx ActiveX object for Internet Explorer 5.01, 6 SP1, and 7 allows remote attackers to execute arbitrary code via unknown vectors related to Microsoft Visual Basic 6 objects and memory corruption, aka "ActiveX Object Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01 and 6 allows remote attackers to execute arbitrary code by instantiating certain COM objects from Urlmon.dll, which triggers memory corruption during a call to the IObjectSafety function.

Microsoft Internet Explorer 5.01, 6, and 7 allows remote attackers to execute arbitrary code by causing Internet Explorer to access an uninitialized or deleted object, related to prototype variables and table cells, aka "Uninitialized Memory Corruption Vulnerability."

Unspecified vulnerability in Microsoft Internet Explorer 6 allows remote attackers to execute arbitrary code via a crafted Cascading Style Sheets (CSS) tag that triggers memory corruption.
