Stack-based buffer overflow in an ActiveX control in najdisitoolbar.dll in Najdi.si Toolbar 2.0.4.1 allows remote attackers to cause a denial of service (browser crash) or execute arbitrary code via a long Document.Location property value.

The Rediff Toolbar 2.0 ActiveX control in redifftoolbar.dll allows remote attackers to cause a denial of service via unspecified manipulations, possibly involving improper initialization or blank arguments.

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.
