Microsoft Internet Explorer 5.01 and 6 allows certain script to persist across navigations between pages, which allows remote attackers to obtain the window location of visited web pages in other domains or zones, aka "Window Location Information Disclosure Vulnerability."

Cross-site scripting (XSS) vulnerability in Internet Explorer 5.01 and 6 in Microsoft Windows 2000 SP4 permits access to local "HTML-embedded resource files" in the Microsoft Management Console (MMC) library, which allows remote authenticated users to execute arbitrary commands, aka "MMC Redirect Cross-Site Scripting 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."

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."

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.

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.

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.

Microsoft Internet Explorer before Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1, when Prompt is configured in Security Settings, uses modal dialogs to verify that a user wishes to run an ActiveX control or perform other risky actions, which allows user-assisted remote attackers to construct a race condition that tricks a user into clicking an object or pressing keys that are actually applied to a "Yes" approval for executing the control.
