Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to misrepresent the source of a file in the File Download dialogue box to trick users into thinking that the file type is safe to download, aka "File Origin Spoofing."

Internet Explorer 5.01 through 6 allows remote attackers to spoof arbitrary web sites by injecting content from one window into another window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability. NOTE: later research shows that Internet Explorer 7 on Windows XP SP2 is also vulnerable.

Internet Explorer 5.5 allows remote attackers to bypass security restrictions via malformed URLs that contain dotless IP addresses, which causes Internet Explorer to process the page in the Intranet Zone, which may have fewer security restrictions, aka the "Zone Spoofing Vulnerability variant" of CVE-2001-0664.

Internet Explorer 5.5 and 6.0 does not perform complete security checks on external caching, which allows remote attackers to read arbitrary files.

Microsoft Internet Explorer 5.01, 5.5 and 6.0 does not properly check parameters that are passed during third party rendering, which could allow remote attackers to execute arbitrary web script, aka the "Third Party Plugin Rendering" vulnerability, a different vulnerability than CVE-2003-0233.

Internet Explorer 5.x and 6 interprets an object as an HTML document even when its MIME Content-Type is text/plain, which could allow remote attackers to execute arbitrary script in documents that the user does not expect, possibly through web applications that use a text/plain type to prevent cross-site scripting attacks.

Microsoft Internet Explorer 5.01, 5.5 and 6.0 treats objects invoked on an HTML page with the codebase property as part of Local Computer zone, which allows remote attackers to invoke executables present on the local system through objects such as the popup object, aka the "Local Executable Invocation via Object tag" vulnerability.

Microsoft Windows Internet Explorer 5.5 and 6.0 allows remote attackers to execute arbitrary code via an embedded script that uses Shell Helper objects and a shortcut (link) to execute the target script.

Internet Explorer 5, 5.6, and 6 allows remote attackers to bypass cookie privacy settings and store information across browser sessions via the userData (storeuserData) feature.

Microsoft Internet Explorer allows remote attackers to bypass intended cookie access restrictions on a web application via "%2e%2e" (encoded dot dot) directory traversal sequences in a URL, which causes Internet Explorer to send the cookie outside the specified URL subsets, e.g. to a vulnerable application that runs on the same server as the target application.

Multiple unspecified vulnerabilities in DirectAnimation ActiveX controls for Microsoft Internet Explorer 5.01 through 6 have unknown impact and remote attack vectors, possibly related to (1) Danim.dll and (2) Lmrt.dll, a different set of vulnerabilities than CVE-2006-4446 and CVE-2006-4777.

The rendering engine in Internet Explorer determines the MIME type independently of the type that is specified by the server, which allows remote servers to automatically execute script which is placed in a file whose MIME type does not normally support scripting, such as text (.txt), JPEG (.jpg), etc.

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.

File Download box in Internet Explorer 5.01, 5.5 and 6.0 allows an attacker to use the Content-Disposition and Content-Type HTML header fields to modify how the name of the file is displayed, which could trick a user into believing that a file is safe to download.
