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."
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 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."
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.
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.
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.
Microsoft Internet Explorer 6 SP2 allows remote attackers to cause a denial of service (infinite loop and application crash) via two embedded files that call each other.
Internet Explorer 5.01, 5.5, and 6 does not properly validate buffers when handling certain DHTML methods including the createControlRange Javascript function, which allows remote attackers to execute arbitrary code, aka the "DHTML Method Heap Memory Corruption Vulnerability."
