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.
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.
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.
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.
wininet.dll in Microsoft Internet Explorer 6.0 SP2 and earlier allows remote attackers to cause a denial of service (unhandled exception and crash) via a long Content-Type header, which triggers a stack overflow.
Microsoft Internet Explorer before Windows XP Service Pack 2 and Windows Server 2003 Service Pack 1, when Prompt is configured in Security Settings, uses modal dialogs to verify that a user wishes to run an ActiveX control or perform other risky actions, which allows user-assisted remote attackers to construct a race condition that tricks a user into clicking an object or pressing keys that are actually applied to a "Yes" approval for executing the control.
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.
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.
The download function of Internet Explorer 6 SP1 allows remote attackers to obtain the cache directory name via an HTTP response with an invalid ContentType and a .htm file, which could allow remote attackers to bypass security mechanisms that rely on random names, as demonstrated by threadid10008.
Certain versions of Internet Explorer 5 and 6, in certain Windows environments, allow remote attackers to cause a denial of service (freeze) via a URL to C:\aux (MS-DOS device name) and possibly other devices.
Microsoft Internet Explorer 6.0 and possibly others allows remote attackers to upload arbitrary file contents when users press a key corresponding to the JavaScript (1) event.ctrlKey or (2) event.shiftKey onkeydown event contained in a webpage. NOTE: it was reported that the vendor has disputed the severity of this issue.
Internet Explorer 5.0, 5.0.1 and 5.5 with JavaScript execution enabled allows remote attackers to determine the existence of arbitrary files via a script tag with a src parameter that references a non-JavaScript file, then using the onError event handler to monitor the results.
Microsoft Internet Explorer 5.0, 5.01, and 5.5 allows remote attackers to monitor the contents of the clipboard via the getData method of the clipboardData object.
Microsoft Internet Explorer 5.0 through 6.0 allows remote attackers to cause a denial of service (crash) via an object of type "text/html" with the DATA field that identifies the HTML document that contains the object, which may cause infinite recursion.
Cross-site scripting vulnerability (XSS) in Internet Explorer 5.01 through 6.0 allows remote attackers to read and execute files on the local system via web pages using the <frame> or <iframe> element and javascript, aka "Frames Cross Site Scripting," as demonstrated using the PrivacyPolicy.dlg resource.
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.
Internet Explorer 5.0 through 6.0 allows remote attackers to determine the existence of files on the client via an IMG tag with a dynsrc property that references the target file, which sets certain elements of the image object such as file size.
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 via the frame, aka the "Frame Domain Verification" vulnerability.
The window.showHelp() method in Internet Explorer 5.x does not restrict HTML help files (.chm) to be executed from the local host, which allows remote attackers to execute arbitrary commands via Microsoft Networking.
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 5.01 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."
Internet Explorer 5 allows a remote attacker to modify the IE client's proxy configuration via a malicious Web Proxy Auto-Discovery (WPAD) server.
Windows Media Player ActiveX object as used in Internet Explorer 5.0 returns a specific error code when a file does not exist, which allows remote malicious web sites to determine the existence of files on the client.
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.
Internet Explorer 5 allows remote attackers to read files via an ExecCommand method called on an IFRAME.
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.
The "download behavior" in Internet Explorer 5 allows remote attackers to read arbitrary files via a server-side redirect.
