title: COCOS2DX libpng Google Play Notification June 2016
body: <p>I have received notification on my many apps on Google Play all developed in <strong>COCOS2DX</strong>, the Notification states that there is a <strong>security vulnerability in libpng</strong>, I am sure this is in cocos2dX because I haven't received them on games developed in AndEngine or Unity.
  We are using <strong>COCOS2DX version 2.2, 2.1.2 and 2.2.6</strong> and we need to fix this ASAP
  Can any one suggest a solution for this problem? We cannot move to new COCOS2dX Version because we have many game so we need to fix the old version.
  Thanks</p>
