Microsoft Internet Explorer 6 allows remote attackers to execute arbitrary code by using the document.getElementByID Javascript function to access crafted Cascading Style Sheet (CSS) elements, and possibly other unspecified vectors involving certain layout positioning combinations in an HTML file.

Microsoft Internet Explorer 5 SP4 and 6 do not properly garbage collect when "multiple imports are used on a styleSheets collection" to construct a chain of Cascading Style Sheets (CSS), which allows remote attackers to execute arbitrary code via unspecified vectors.

Microsoft Internet Explorer 5.01 SP4 and 6 does not properly handle various HTML layout component combinations, which allows user-assisted remote attackers to execute arbitrary code via a crafted HTML file that leads to memory corruption, aka "HTML Rendering Memory Corruption Vulnerability."

Microsoft Internet Explorer 5.01 and 6 does not properly handle uninitialized COM objects, which allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code, as demonstrated by the Nth function in the DirectAnimation.DATuple ActiveX control, aka "COM Object Instantiation Memory Corruption Vulnerability."

Stack-based buffer overflow in NDFXArtEffects in Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) via long (1) RGBExtraColor, (2) RGBForeColor, and (3) RGBBackColor properties.

Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) via a (1) Forms.ListBox.1 or (2) Forms.ListBox.1 object with the ListWidth property set to (a) 0x7fffffff, which triggers an integer overflow exception, or to (b) 0x7ffffffe, which triggers a null dereference.

Internet Explorer 6 on Windows XP SP2, when Outlook is installed, allows remote attackers to cause a denial of service (crash) by calling the NewDefaultItem function of an OVCtl (OVCtl.OVCtl.1) ActiveX object, which triggers a null dereference.

Integer overflow in Microsoft Internet Explorer 6 on Windows XP SP2 allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a 0x7fffffff argument to the setSlice method on a WebViewFolderIcon ActiveX object, which leads to an invalid memory copy.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (stack overflow exception) via a DXImageTransform.Microsoft.Gradient ActiveX object with a long (1) StartColorStr or (2) EndColorStr property.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by accessing the object references of a FolderItem ActiveX object, which triggers a null dereference in the security check.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by setting the location or URL property of a MHTMLFile ActiveX object.

danim.dll in Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (application crash) by accessing the Data property of a DirectAnimation DAUserData object before it is initialized, which triggers a NULL pointer dereference.

The Remote Data Service Object (RDS.DataControl) in Microsoft Internet Explorer 6 on Windows 2000 allows remote attackers to cause a denial of service (crash) via a series of operations that result in an invalid length calculation when using SysAllocStringLen, then triggers a buffer over-read.

Microsoft Internet Explorer 6.0 and 6.0 SP1 allows remote attackers to cause a denial of service via an HTML page with an A tag containing a long title attribute. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Microsoft Internet Explorer 6 on Windows XP allows remote attackers to cause a denial of service (crash) via a table with a frameset as a child, which triggers a null dereference, as demonstrated using the appendChild method.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (crash) by setting the Filter property of an ADODB.Recordset ActiveX object to certain values multiple times, which triggers a null dereference.

Multiple unspecified vulnerabilities in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allow remote attackers to execute arbitrary code by instantiating certain COM objects from Wmm2fxa.dll as ActiveX controls including (1) DXImageTransform.Microsoft.MMSpecialEffect1Input, (2) DXImageTransform.Microsoft.MMSpecialEffect1Input.1, (3) DXImageTransform.Microsoft.MMSpecialEffect2Inputs, (4) DXImageTransform.Microsoft.MMSpecialEffect2Inputs.1, (5) DXImageTransform.Microsoft.MMSpecialEffectInplace1Input, and (6) DXImageTransform.Microsoft.MMSpecialEffectInplace1Input.1, which causes memory corruption during garbage collection.

Buffer overflow in the ART Image Rendering component (jgdw400.dll) in Microsoft Windows XP SP1 and Sp2, Server 2003 SP1 and earlier, and Windows 98 and Me allows remote attackers to execute arbitrary code via a crafted ART image that causes heap corruption.

Unspecified vulnerability in Microsoft Internet Explorer 5.01 SP4 and 6 SP1 and earlier allows user-assisted remote attackers to execute arbitrary code via a crafted web page that triggers memory corruption when it is saved as a multipart HTML (.mht) file.

Internet Explorer 6 allows user-assisted remote attackers to read arbitrary files by tricking a user into typing the characters of the target filename in a text box and using the OnKeyDown, OnKeyPress, and OnKeyUp Javascript keystroke events to change the focus and cause those characters to be inserted into a file upload input control, which can then upload the file when the user submits the form.
