Heap-based buffer overflow in DirectAnimation.PathControl COM object (daxctle.ocx) in Microsoft Internet Explorer 6.0 SP1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a Spline function call whose first argument specifies a large number of points.

Heap-based buffer overflow in URLMON.DLL in Microsoft Internet Explorer 6 SP1 on Windows 2000 and XP SP1, with versions the MS06-042 patch before 20060824, allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a long URL on a website that uses HTTP 1.1 compression.

Microsoft Internet Explorer 6.0 SP1 allows remote attackers to cause a denial of service (crash) via a long Color attribute in multiple DirectX Media Image DirectX Transforms ActiveX COM Objects from (a) dxtmsft.dll and (b) dxtmsft3.dll, including (1) DXImageTransform.Microsoft.MaskFilter.1, (2) DXImageTransform.Microsoft.Chroma.1, and (3) DX3DTransform.Microsoft.Shapes.1.

The Terminal Services COM object (tsuserex.dll) allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by instantiating it as an ActiveX object in Internet Explorer 6.0 SP1 on Microsoft Windows 2003 EE SP1 CN.

Microsoft Internet Explorer 6.0 SP1 and possibly other versions allows remote attackers to cause a denial of service and possibly execute arbitrary code by instantiating COM objects as ActiveX controls, including (1) imskdic.dll (Microsoft IME), (2) chtskdic.dll (Microsoft IME), and (3) msoe.dll (Outlook), which leads to memory corruption. NOTE: it is not certain whether the issue is in Internet Explorer or the individual DLL files.

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."

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.
