Microsoft Internet Explorer 4.0 Patch External JScript Vulnerability Description

From Microsoft: Microsoft Internet Explorer 4.0, 4.01, and 4.01 SP1 use the JScript Scripting Engine version 3.1 to process scripts on a Web page. When Internet Explorer encounters a web page that uses JScript script to invoke the Window.External function with a very long string, Internet Explorer could terminate. Long strings do not normally occur in scripts and must be intentionally created by someone with malicious intent. A skilled hacker could use this malicious script message to run arbitrary computer code contained in the long string. In order for users to be affected by this problem, they must visit a Web site that was intentionally designed to include a malicious script. See the "Administrative Workaround" section later in the document for more information.
