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.
Microsoft Internet Explorer 6 allows remote attackers to spoof the address bar to facilitate phishing attacks via Javascript that uses an invalid URI, modifies the Location field, then uses history.back to navigate to the previous domain, aka NullyFake.
Microsoft Internet Explorer 5.5 and 6.0 allocates memory based on the memory size written in the BMP file instead of the actual BMP file size, which allows remote attackers to cause a denial of service (memory consumption) via a small BMP file with has a large memory size.

DataSourceControl in Internet Explorer 6 on Windows XP SP2 with Office installed allows remote attackers to cause a denial of service (crash) via a large negative integer argument to the getDataMemberName method of a OWC11.DataSourceControl.11 object, which leads to an integer overflow and a null dereference.
Buffer overflow in INETCOMM.DLL, as used in Microsoft Internet Explorer 6.0 through 6.0 SP2, Windows Explorer, Outlook Express 6, and possibly other programs, allows remote user-assisted attackers to cause a denial of service (application crash) via a long mhtml URI in the URL value in a URL file.
