The remote host contains a web browser that is vulnerable to remote code execution attacks.
The version of Google Chrome installed on the remote host is earlier than 18.104.22.168. Such versions are potentially affected by a security bypass vulnerability caused by custom headers being incorrectly sent for 'CORS OPTIONS' requests. A malicious web site operator could set custom HTTP headers on cross-origin 'OPTIONS' requests.
Upgrade to Google Chrome 22.214.171.124 or later.
