| Detailed Description |
Internet Explorer 'Font Download' option is set less than the value defined in the security policy. Malicious nonstandard fonts used on web page may be automatically downloaded on the local computer, although the user doesn't know.
Internet Explorer includes five predefined zones: Internet, Local Intranet, Trusted Sites, Restricted Sites, and My Computer. User can set the security options that user wants for each zone, and then add or remove Web sites from the zones, depending on your level of trust in a Web site. This option for each security zone manages whether or not new fonts should be directly downloaded from HTML page including the download link in the security zone.
* Note: This check requires an account with Guest or upper privileges which can access the registry of the remote host to scan. Absence of these condition will result in the check not being performed and a False Negative for all vulnerable hosts. Unless the user applies the new policy of security zones, the default value of this option is set to the default setting value of the security zone that applied in Internet Explorer 5.
