Microsoft Internet Explorer 5.0.1

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.

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.

Buffer overflow in the ART Image Rendering component (jgdw400.dll) in Microsoft Windows XP SP1 and Sp2, Server 2003 SP1 and earlier, and Windows 98 and Me allows remote attackers to execute arbitrary code via a crafted ART image that causes heap corruption.

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 5.01 through 6.0 allows remote attackers to identify the path to the Temporary Internet Files folder and obtain user information such as cookies via certain uses of the OBJECT tag, which are not subjected to the proper security checks, aka "Temporary Internet Files folders Name Reading."

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.

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 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 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.

Multiple design errors in Microsoft Internet Explorer 5.01, 5.5, and 6 allow user-assisted attackers to execute arbitrary code by (1) overlaying a malicious new window above a file download box, then (2) using a keyboard shortcut and delaying the display of the file download box until the user hits a shortcut that activates the "Run" button, aka "File Download Dialog Box Manipulation Vulnerability."

Internet Explorer 6.x allows remote attackers to install arbitrary programs via mousedown events that call the Popup.show method and use drag-and-drop actions in a popup window, aka "HijackClick 3" and the "Script in Image Tag File Download Vulnerability."

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 5.01, 5.5, and 6, when using an HTTPS proxy server that requires Basic Authentication, sends URLs in cleartext, which allows remote attackers to obtain sensitive information, aka "HTTPS Proxy Vulnerability."

Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html".

Microsoft Internet Explorer 5.01, 5.5 and 6.0 does not properly check the Cascading Style Sheet input parameter for Modal dialogs, which allows remote attackers to read files on the local system via a web page containing script that creates a dialog and then accesses the target files, aka "Modal Dialog script execution."

Internet Explorer 5.01 through 6 allows remote attackers to cause a denial of service (application crash) via Javascript in a web page that calls location.replace on itself, causing a loop.

Internet Explorer 5.01 through 6.0 does not properly check certain parameters of a PNG file when opening it, which allows remote attackers to cause a denial of service (crash) by triggering a heap-based buffer overflow using invalid length codes during decompression, aka "Malformed PNG Image File Failure."

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.

Internet Explorer 5.01 through 6.0 does not properly perform security checks on certain encoded characters within a URL, which allows a remote attacker to steal potentially sensitive information from a user by redirecting the user to another site that has that information, aka "Encoded Characters Information Disclosure."

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.

Internet Explorer 6.0 and earlier does not properly handle VBScript in certain domain security checks, which allows remote attackers to read arbitrary files.

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.

Microsoft Internet Explorer 5.0.1 through 6.0 allows remote attackers to determine the existence of arbitrary files via the VBScript LoadPicture method, which returns an error code if the file does not exist.

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.

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.

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 file upload control in Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to automatically upload files from the local system via a web page containing a script to upload the files.

Microsoft Internet Explorer 6.0.2900.2180 and earlier allows remote attackers to cause a denial of service (CPU consumption and application hang) via JavaScript code with a long string value for the hash property (aka location.hash), a related issue to CVE-2008-5715.

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 5.0.1 through 6.0 on Windows 2000 or Windows XP allows remote attackers to cause a denial of service (crash) via an OBJECT tag that contains a crafted CLASSID (CLSID) value of "CLSID:00022613-0000-0000-C000-000000000046".

Microsoft Internet Explorer 8 and earlier, and Internet Explorer 9 beta, does not properly restrict cross-zone drag-and-drop actions, which allows user-assisted remote attackers to read cookie files via vectors involving an IFRAME element with a SRC attribute containing a file: URL, as demonstrated by a Facebook game, related to a "cookiejacking" issue.

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.

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 "/.#./".
