Patch Available for New Variant of "Scriptlet Rendering" Vulnerability

Microsoft has released an update to Internet Explorer that addresses a potential security issue that could enable a malicious Web site operator to provide incorrect information that consists of script, solely for the purpose of introducing it into an Internet Explorer system file with a known name to use the OBJECT tag to render the file. The net effect would be to make the script run in the Local Computer zone, at which point it could obtain access to files on the user's local file system. As of 12/12/2000, this patch eliminates all known variants of this vulnerability.
