Yesterday, Adobe announced updates for several of its main products, including Flash, Acrobat Reader, and Shockwave.

Flash 27.0.0.187 addresses five critical vulnerabilities in earlier versions. You can download the new desktop version from the main Flash download page. That page usually offers to install additional software, which you should avoid. Chrome will as usual update itself with the new version, and both Internet Explorer and Edge will get their own updates via Windows Update.

Acrobat Reader 11.0.23 includes fixes for a whopping sixty-two vulnerabilities, all flagged as critical, in earlier versions. Download the full installer from the Acrobat Reader Download Center.

Shockwave Player 12.3.1.201 addresses a single critical security issue in earlier versions. Download the new version from the Adobe Shockwave Player Download Center.

If you use Flash, Reader or Shockwave to view content from untrusted sources, or if you use a web browser with add-ons enabled for any of these technologies, you should update affected systems immediately.
