[On October 14th, 2014, Google engineers disclosed a vulnerability in an older encryption protocol called SSLv3. Users of older web browsers that use this protocol exclusively, such as Internet Explorer 6, are exposed to possible "man-in-the-middle" attacks. In addition, more recent browser versions that use more modern encryption protocols such as TLS are not exempted, as these browsers may be forced to fall-back to using SSLv3 by an attacker.]
