Drivers for certain display adapters, including (1) an unspecified ATI driver and (2) an unspecified Intel driver, might allow remote attackers to cause a denial of service (system crash) via a large JPEG image, as demonstrated in Internet Explorer using stoopid.jpg with a width and height of 9999999.

Microsoft Internet Explorer allows remote attackers to bypass cross-domain security restrictions and obtain sensitive information by using the @import directive to download files from other domains that are not valid Cascading Style Sheets (CSS) files, as demonstrated using Google Desktop, aka "CSSXSS" and "CSS Cross-Domain Information Disclosure Vulnerability."

Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to misrepresent the source of a file in the File Download dialogue box to trick users into thinking that the file type is safe to download, aka "File Origin Spoofing."

The HTML rendering engine in Microsoft Internet Explorer 6.0 allows remote attackers to conduct cross-site scripting (XSS) attacks via HTML in corrupted images and other files such as .GIF, JPG, and WAV, which is rendered as HTML when the user clicks on the link, even though the web server response and file extension indicate that it should be treated as a different file type.

Race condition in Microsoft Internet Explorer allows user-assisted attackers to overwrite arbitrary files and possibly execute code by tricking a user into performing a drag-and-drop action from certain objects, such as file objects within a folder view, then predicting the drag action, and re-focusing to a malicious window.

Microsoft Internet Explorer 5.01 and 5.5 allows remote attackers to execute scripts in the Local Computer zone via a URL that references a local HTML resource file, a variant of "Cross-Site Scripting in Local HTML Resource" as identified by CAN-2002-0189.

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 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.

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet Explorer, aka a variant of the "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2127.

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."

The legacy <script> data-island capability for XML in Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to read arbitrary XML files, and portions of other files, via a URL whose "src" attribute redirects to a local file.

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."

Microsoft MSN Messenger 9.0 and Internet Explorer 6.0 allows remote attackers to cause a denial of service (crash) via an image with an ICC Profile with a large Tag Count.

Buffer overflow in a legacy ActiveX control used to display specially formatted text in Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to execute arbitrary code, aka "Buffer Overrun in Legacy Text Formatting ActiveX Control".

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.

Microsoft Internet Explorer 6.0 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability."

Internet Explorer 5.01 SP4 up to 6 on various Windows operating systems, including IE 6.0.2900.2180 on Windows XP, allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not ActiveX controls, as demonstrated using the JVIEW Profiler (Javaprxy.dll). NOTE: the researcher says that the vendor could not reproduce this problem.

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 5.0, 5.5, and 6.0 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not ActiveX controls, including (1) devenum.dll, (2) diactfrm.dll, (3) wmm2filt.dll, (4) fsusd.dll, (5) dmdskmgr.dll, (6) browsewm.dll, (7) browseui.dll, (8) shell32.dll, (9) mshtml.dll, (10) inetcfg.dll, (11) infosoft.dll, (12) query.dll, (13) syncui.dll, (14) clbcatex.dll, (15) clbcatq.dll, (16) comsvcs.dll, and (17) msconf.dll, which causes memory corruption, aka "COM Object Instantiation Memory Corruption Vulnerability," a different vulnerability than CVE-2005-2087.

Unknown vulnerability in Internet Explorer 5.0, 5.5, and 6.0 allows remote attackers to obtain information and possibly execute code when browsing from a web site to a web folder view using WebDAV, aka "Web Folder Behaviors Cross-Domain Vulnerability".
