Flash users, it's time to update the plugin ASAP. Adobe has today issued an emergency security update to patch a critical vulnerability, just three days after the last update. Adobe says the vulnerability could potentially give an attacker control of an affected system. This update will bring the Flash NPAPI plugin up to version 19.0.0.226 on Windows and OS X clients. Chrome and Edge will automatically update themselves with the latest plugins for those browsers, according to the security bulletin. Peter Pi of Trend Micro says this vulnerability could allow attackers to get around mitigation techniques that Adobe and Google created together if it's left unpatched
