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.

ICQLite 2003a creates the ICQ Lite directory with an ACE for "Full Control" privileges for Interactive Users, which allows local users to gain privileges as other users by replacing the executables with malicious programs.
