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.
Internet Explorer 5.0 and 5.01 allows remote attackers to modify or execute files via the Import/Export Favorites feature, aka the "ImportExportFavorites" vulnerability.
Internet Explorer 4.x and 5.x allows remote attackers to execute arbitrary commands via a buffer overflow in the ActiveX parameter parsing capability, aka the "Malformed Component Attribute" 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.
Buffer overflow in Internet Explorer 4.01 and earlier allows remote attackers to execute arbitrary commands via a long URL with the "mk:" protocol, aka the "MK Overrun security issue."
Internet Explorer 4 treats a 32-bit number ("dotless IP address") in the a URL as the hostname instead of an IP address, which causes IE to apply Local Intranet Zone settings to the resulting web page, allowing remote malicious web servers to conduct unauthorized activities by using URLs that contain the dotless IP address for their server.
Internet Explorer 4.0 and 5.0 allows a remote attacker to execute security scripts in a different security context using malicious URLs, a variant of the "cross frame" vulnerability.
Buffer overflow in Internet Explorer 4.0(1).
Internet Explorer 4.0 and later allows remote attackers to read arbitrary files via a web page that accesses a legacy XML Datasource applet (com.ms.xml.dso.XMLDSO.class) and modifies the base URL to point to the local system, which is trusted by the applet.
Microsoft Internet Explorer before 8 displays a cached certificate for a (1) 4xx or (2) 5xx CONNECT response page returned by a proxy server, which allows man-in-the-middle attackers to spoof an arbitrary https site by letting a browser obtain a valid certificate from this site during one request, and then sending the browser a crafted 502 response page upon a subsequent request.
Microsoft Internet Explorer before 8 uses the HTTP Host header to determine the context of a document provided in a (1) 4xx or (2) 5xx CONNECT response from a proxy server, which allows man-in-the-middle attackers to execute arbitrary web script by modifying this CONNECT response, aka an "SSL tampering" attack.
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.
Buffer overflow in Registration Wizard ActiveX control (regwizc.dll, InvokeRegWizard) 3.0.0.0 for Internet Explorer 4.01 and 5 allows remote attackers to execute arbitrary commands.
The Kodak/Wang (1) Image Edit (imgedit.ocx), (2) Image Annotation (imgedit.ocx), (3) Image Scan (imgscan.ocx), (4) Thumbnail Image (imgthumb.ocx), (5) Image Admin (imgadmin.ocx), (6) HHOpen (hhopen.ocx), (7) Registration Wizard (regwizc.dll), and (8) IE Active Setup (setupctl.dll) ActiveX controls for Internet Explorer (IE) 4.01 and 5.0 are marked as "Safe for Scripting," which allows remote attackers to create and modify files and execute arbitrary commands.
Buffer overflow in HHOpen ActiveX control (hhopen.ocx) 1.0.0.1 for Internet Explorer 4.01 and 5 allows remote attackers to execute arbitrary commands via long arguments to the OpenHelp method.
Buffer overflow in the Window.External function in the JScript Scripting Engine in Internet Explorer 4.01 SP1 and earlier allows remote attackers to execute arbitrary commands via a malicious web page.
Internet Explorer 5.01 and earlier allows a remote attacker to create a reference to a client window and use a server-side redirect to access local files via that window, aka "Server-side Page Reference Redirect."
jscript.dll in Microsoft Internet Explorer 6.0 SP1 and earlier allows remote attackers to cause a denial of service (application crash) via a Shockwave Flash object that contains ActionScript code that calls VBScript, which in turn calls the Javascript document.write function, which triggers a null dereference.
The JavaScript implementation in Microsoft Internet Explorer 8.0 and earlier does not properly restrict the set of values contained in the object returned by the getComputedStyle method, which allows remote attackers to obtain sensitive information about visited web pages by calling this method.
Microsoft Internet Explorer 6.0.2900.2180 and earlier allows remote attackers to cause a denial of service (CPU and memory consumption) via a long Unicode string argument to the write method, a related issue to CVE-2009-2479. NOTE: it was later reported that 7.0.6000.16473 and earlier are also affected.
The Cascading Style Sheets (CSS) implementation in Microsoft Internet Explorer 8.0 and earlier does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.
Microsoft Internet Explorer 4.0 through 7 allows remote attackers to determine the existence of local files that have associated images via a res:// URI in the src property of a JavaScript Image object, as demonstrated by the URI for a bitmap image resource within a (1) .exe or (2) .dll file.
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 4.01 allows remote attackers to read arbitrary files by pasting a file name into the file upload control, aka untrusted scripted paste.
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.
Internet Explorer allows remote attackers to read files by redirecting data to a Javascript applet.
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.
