A new version of Flash, released yesterday, addresses at least thirteen vulnerabilities in previous versions.

According to the security bulletin for Flash 24.0.0.221, the new version fixes “critical vulnerabilities that could potentially allow an attacker to take control of the affected system.”

The release notes for Flash 24.0.0.221 describe some new features that are likely only of interest to developers.

As usual, Internet Explorer and Edge will get new versions of their embedded Flash via Windows Update, while Chrome’s embedded Flash will be updated automatically.

Anyone who still uses a web browser with Flash enabled should update it as soon as possible.
