Cross-site scripting (XSS) vulnerability in Google Toolbar 2.0.114.1 allows remote attackers to inject arbitrary web script via about.html in the About section. NOTE: some followup posts suggest that the demonstration code's use of the res:// protocol does not cross privilege boundaries, since it is not allowed in the Internet Zone. Thus this might not be a vulnerability.

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.
