When was the last time you updated your WordPress website? Its easy to not get round to these admin tasks.
Well a security issue has been identified, affecting the WordPress platform. This platform is vulnerable to attacks that leverage the PHP XML parser to exhaust server resources, which can result slow-loading pages or complete unavailability.
So I would recommend updating to the most recent version as soon as possible. The latest release that patches the vulnerability is provided below:
WordPress Version 3.9.2
