Adobe patches “critical” Flash Player bug that could expose users to malware

Adobe has shipped a patch for a critical vulnerability affecting Flash Player on Windows, macOS, Linux and Chrome OS.

The vulnerability, known as a type confusion bug, enables remote code execution, and could allow hackers to install malware on the computers of users who have visited web pages hosting malicious Flash files.

In a security bulletin published on Tuesday (20 November), Adobe urged users running Flash to update to Users can verify which version they are running by visiting the company’s “About Flash Player” web page.

Last year, Adobe announced it would shut down the Flash Player plug-in by the end of 2020. The software has been widely superceded in recent years by HTML5, which lets users watch videos without installing a dedicated plugin.

Adobe did not instantly respond to a request for comment.
