This patch eliminates four security vulnerabilities in Microsoft Internet Explorer 5.x: The 'Browser Print Template' vulnerability, which could enable a malicious Web site operator to take unauthorized actions on the computer of a user who visited their site. The 'File Upload via Form' vulnerability, which could enable a malicious Web site operator to read files on a visiting user’s computer. New variants of the 'Scriptlet Rendering' and 'Frame Domain Verification' vulnerabilities, both of which could enable a malicious Web site operator to read files on a visiting user’s computer.
