Buffer overflow in the IEToolbar.IEContextMenu.1 ActiveX control in LinkedInIEToolbar.dll in the LinkedIn Toolbar 3.0.2.1098 allows remote attackers to execute arbitrary code via a long second argument (varBrowser argument) to the search method. NOTE: some of these details are obtained from third party information.

Buffer overflow in the isChecked function in toolbar.dll in Netsprint Toolbar 1.1 might allow remote attackers to execute arbitrary code via unspecified vectors.

Unspecified vulnerability in the GetPropertyById function in ISoftomateObj in SoftomateLib in BRUJULA4.NET.DLL in the Brujula Toolbar (Brujula.net toolbar) allows attackers to cause a denial of service (NULL dereference and browser crash) via certain arguments.

A certain ActiveX control in askPopStp.dll in Netsprint Ask IE Toolbar 1.1 allows remote attackers to cause a denial of service (Internet Explorer crash) via a long AddAllowed property value, related to "improper memory handling," possibly a buffer overflow.

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.

Multiple cross-site scripting (XSS) vulnerabilities in the RSS Feed module in AOL ICQ Toolbar 1.3 for Internet Explorer (toolbaru.dll) allow remote attackers to process arbitrary web script or HTML in the Feeds interface context via the (1) title and (2) description elements within an item element in an RSS feed.

AOL ICQ Toolbar 1.3 for Internet Explorer (toolbaru.dll) does not properly validate the origin of the configuration web page (options2.html), which allows user-assisted remote attackers to provide a web page that contains disguised checkboxes that trick the user into reconfiguring the toolbar.

Stack-based buffer overflow in the SetSkin function in AtHoc toolbar allows remote attackers to execute arbitrary code via a long skin name.

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.

Format string vulnerability in the SetBaseURL function in AtHoc toolbar allows remote attackers to execute arbitrary code via format string specifiers in an invalid URL that is recorded in the debug log.
