MSHTML.DLL HTML parser in Internet Explorer 4.0, and other versions, allows remote attackers to cause a denial of service (application crash) via a script that creates and deletes an object that is associated with the browser window 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 "/.#./".

HTML e-mail feature in Internet Explorer 5.5 and earlier allows attackers to execute attachments by setting an unusual MIME type for the attachment, which Internet Explorer does not process correctly.

Internet Explorer 5.0 and 5.5, and Outlook Express 5.0 and 5.5, allow remote attackers to execute scripts when Active Scripting is disabled by including the scripts in XML stylesheets (XSL) that are referenced using an IFRAME tag, possibly due to a vulnerability in Windows Scripting Host (WSH).

The Print Templates feature in Internet Explorer 5.5 executes arbitrary custom print templates without prompting the user, which could allow an attacker to execute arbitrary ActiveX controls, aka the "Browser Print Template" vulnerability.

Internet Explorer 5.0 through 5.5 allows remote attackers to read arbitrary files from the client via the INPUT TYPE element in an HTML form, aka the "File Upload via Form" vulnerability.

The ActiveX control for invoking a scriptlet in Internet Explorer 5.0 through 5.5 renders arbitrary file types instead of HTML, which allows an attacker to read arbitrary files, aka a variant of the "Scriptlet Rendering" vulnerability.

Internet Explorer before 5.5 forwards cached user credentials for a secure web site to insecure pages on the same web site, which could allow remote attackers to obtain the credentials by monitoring connections to the web server, aka the "Cached Web Credentials" vulnerability.

The ActiveX control for invoking a scriptlet in Internet Explorer 4.x and 5.x renders arbitrary file types instead of HTML, which allows an attacker to read arbitrary files, aka the "Scriptlet Rendering" vulnerability.
