Internet Explorer 4.x and 5.x allows remote web servers to access files on the client that are outside of its security domain, aka the "Image Source Redirect" vulnerability.

Internet Explorer 5 allows remote attackers to read files via an ExecCommand method called on an IFRAME.

Internet Explorer 6.x allows remote attackers to install arbitrary programs via mousedown events that call the Popup.show method and use drag-and-drop actions in a popup window, aka "HijackClick 3" and the "Script in Image Tag File Download Vulnerability."

Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html".

Stack consumption vulnerability in Internet Explorer The JavaScript settimeout function in Internet Explorer allows remote attackers to cause a denial of service (crash) via the JavaScript settimeout function. NOTE: the vendor could not reproduce the problem.

Microsoft Internet Explorer 6.0.2800.1106 on Microsoft Windows XP SP2, and other versions including 5.01 and 5.5, allows remote web servers to bypass zone restrictions and execute arbitrary code in the local computer zone by redirecting a function to another function with the same name, as demonstrated by SimilarMethodNameRedir, aka the "Similar Method Name Redirection Cross Domain Vulnerability."

Internet Explorer for Mac 5.2.3, Internet Explorer 6 on Windows XP, and possibly other versions, does not properly prevent a frame in one domain from injecting content into a frame that belongs to another domain, which facilitates web site spoofing and other attacks, aka the frame injection vulnerability.

Microsoft Internet Explorer 4.0 through 6.0 could allow local users to differentiate between alphanumeric and non-alphanumeric characters used in a password by pressing certain control keys that jump between non-alphanumeric characters, which makes it easier to conduct a brute-force password guessing attack.

Internet Explorer 5 does not modify the security zone for a document that is being loaded into a window until after the document has been loaded, which could allow remote attackers to execute Javascript in a different security context while the document is loading.

Integer overflow in imgbmp.cxx for Windows 2000 allows remote attackers to execute arbitrary code via a BMP image with a large bfOffBits value.

The WebBrowser ActiveX control, or the Internet Explorer HTML rendering engine (MSHTML), as used in Internet Explorer 6, allows remote attackers to execute arbitrary code in the Local Security context by using the showModalDialog method and modifying the location to execute code such as Javascript, as demonstrated using (1) delayed HTTP redirect operations, and an HTTP response with a Location: header containing a "URL:" prepended to a "ms-its" protocol URI, or (2) modifying the location attribute of the window, as exploited by the Download.ject (aka Scob aka Toofer) using the ADODB.Stream object.

Microsoft Internet Explorer 5.0 through 6.0 allows attackers to cause a denial of service (browser crash) via a crafted FTP URL such as "/.#./".

Unknown versions of Internet Explorer and Outlook allow remote attackers to spoof a legitimate URL in the status bar via A HREF tags with modified "alt" values that point to the legitimate site, combined with an image map whose href points to the malicious site, which facilitates a "phishing" attack.

mshtml.dll in Microsoft Internet Explorer 6.0.2800 allows remote attackers to cause a denial of service (crash) via a table containing a form that crosses multiple td elements, and whose "float: left" class is defined in a link to a CSS stylesheet after the end of the table, which may trigger a null dereference.

Internet Explorer 6 and earlier allows remote attackers to create chromeless windows using the Javascript window.createPopup method, which could allow attackers to simulate a victim's display and conduct unauthorized activities or steal sensitive data via social engineering.

Internet Explorer 5.0 and 5.01 allows remote attackers to bypass the cross frame security policy and read files via the external.NavigateAndFind function.

Buffer overflow in Internet Explorer 4.0 via EMBED tag.

The scriptlet.typelib ActiveX control is marked as "safe for scripting" for Internet Explorer, which allows a remote attacker to execute arbitrary commands as demonstrated by Bubbleboy.

Internet Explorer 5.0 allows a remote server to read arbitrary files on the client's file system using the Microsoft Scriptlet Component.

Buffer overflow in Internet Explorer 4.0(1).
