The Google toolbar 1.1.60, when running on Internet Explorer 5.5 and 6.0, allows remote attackers to cause a denial of service (crash with an exception in oleaut32.dll) via malicious HTML, possibly related to small width and height parameters or an incorrect call to the Google.Search() function.
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 5.0 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.
The Javascript "Same Origin Policy" (SOP), as implemented in (1) Netscape, (2) Mozilla, and (3) Internet Explorer, allows a remote web server to access HTTP and SOAP/XML content from restricted sites by mapping the malicious server's parent DNS domain name to the restricted site, loading a page from the restricted site into one frame, and passing the information to the attacker-controlled frame, which is allowed because the document.domain of the two frames matches on the parent domain.
Internet Explorer 5, 5.6, and 6 allows remote attackers to bypass cookie privacy settings and store information across browser sessions via the userData (storeuserData) feature.
Buffer overflow in gopher client for Microsoft Internet Explorer 5.1 through 6.0, Proxy Server 2.0, or ISA Server 2000 allows remote attackers to execute arbitrary code via a gopher:// URL that redirects the user to a real or simulated gopher server that sends a long response.
Microsoft Internet Explorer 5.01 and 6.0 allow remote attackers to execute arbitrary code via malformed Content-Disposition and Content-Type header fields that cause the application for the spoofed file type to pass the file back to the operating system for handling rather than raise an error message, aka the second variant of the "Content Disposition" vulnerability.
Cross-site scripting vulnerability in Internet Explorer 6.0 allows remote attackers to execute scripts in the Local Computer zone via a URL that exploits a local HTML resource file, aka the "Cross-Site Scripting in Local HTML Resource" vulnerability.
Microsoft Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to execute arbitrary code under fewer security restrictions via a malformed web page that requires NetBIOS connectivity, aka "Zone Spoofing through Malformed Web Page" vulnerability.
Microsoft Internet Explorer 5.01, 5.5 and 6.0 allows remote attackers to view arbitrary files that contain the "{" character via script containing the cssText property of the stylesheet object, aka "Local Information Disclosure through HTML Object" vulnerability.
