Microsoft has released an update for Adobe Flash Player that fixes a serious vulnerability in the plugin. The bundled version of the Flash Player plugin is used by Internet Explorer and Edge, so if you use any of those browsers, you should install the update.
This was the only security update that was released instead of the usual collection of updates which are out on Patch Tuesday. The company has delayed its updates March 14th and released this small update, KB4010250 instead.
The Flash update KB4010250 fixes a serious issue documented in the security bulletin MS17-005. The official page comes with the following description of the issue:
This security update resolves vulnerabilities in Adobe Flash Player if Flash Player is installed on any supported edition of Windows Server 2016, Windows Server 2012 R2, Windows Server 2012, Windows 10, Windows 10 Version 1511, Windows 10 Version 1607, Windows 8.1, or Windows RT 8.1.
