Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via a crafted website using Javascript that creates, modifies, deletes, and accesses document objects using the tags property, which triggers heap corruption, related to uninitialized or deleted objects, a different issue than CVE-2007-3902 and CVE-2007-3903, and a variant of "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01 through 7 allows remote attackers to execute arbitrary code via "unexpected method calls to HTML objects," aka "DHTML Object Memory Corruption Vulnerability."

The Web Proxy Auto-Discovery (WPAD) feature in Microsoft Internet Explorer 6 and 7, when a primary DNS suffix with three or more components is configured, resolves an unqualified wpad hostname in a second-level domain outside this configured DNS domain, which allows remote WPAD servers to conduct man-in-the-middle (MITM) attacks.

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.
