As much as I would like to see Flash disappear completely, I have to commend Adobe’s quick response to the recent discovery of a critical Flash exploit.
Flash 18.0.0.203 was released earlier today. The new version fixes the vulnerability associated with the Hacking Team leak (CVE-2015-5119), but it also addresses thirty-five other security vulnerabilities in Flash.
As usual, Google Chrome will update itself with the new Flash code, and Internet Explorer 10 and 11 on Windows 8.x will get the Flash changes via Windows Update.
Recommendation: if you use a web browser with Flash enabled, install the new Flash as soon as possible. Keep in mind that the standard Flash installer also installs McAfee security software by default: look for a checkbox for this option in the installer and disable it.
