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.
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.
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.
A function in Internet Explorer 4.x and 5.x does not properly verify the domain of a frame within a browser window, which allows a remote attacker to read client files, aka a variant of the "Frame Domain Verification" vulnerability.
The IFRAME of the WebBrowser control in Internet Explorer 5.01 allows a remote attacker to violate the cross frame security policy via the NavigateComplete2 event.
Internet Explorer 4.x and 5.x does not properly re-validate an SSL certificate if the user establishes a new SSL session with the same server during the same Internet Explorer session, aka one of two different "SSL Certificate Validation" vulnerabilities.
Internet Explorer 4.x and 5.x does not properly verify all contents of an SSL certificate if a connection is made to the server via an image or a frame, aka one of two different "SSL Certificate Validation" vulnerabilities.
Internet Explorer 4.0 and 5.0 allows a malicious web site to obtain client cookies from another domain by including that domain name and escaped characters in a URL, aka the "Unauthorized Cookie Access" vulnerability.
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.
By default, Internet Explorer 5.0 and other versions enables the "Navigate sub-frames across different domains" option, which allows frame spoofing.
The DHTML Edit ActiveX control in Internet Explorer allows remote attackers to read arbitrary files.
Internet Explorer 4 allows remote attackers (malicious web site operators) to read the contents of the clipboard via the Internet WebBrowser ActiveX object.
Internet Explorer 3.x to 4.01 allows a remote attacker to insert malicious content into a frame of another web site, aka frame spoofing.
Internet Explorer 4.0 and 4.01 allow a remote attacker to read files via IE's cross frame security, aka the "Cross Frame Navigate" vulnerability.
JavaScript in Internet Explorer 3.x and 4.x, and Netscape 2.x, 3.x and 4.x, allows remote attackers to monitor a user's web activities, aka the Bell Labs vulnerability.
