Adobe has released 34 security fixes for Flash Player and Adobe AIR to patch a number of vulnerabilities that leave computer systems wide open to attack.
Windows and Mac users are advised to update Flash Player to version 22.214.171.124 and Linux users to version 126.96.36.1998. Users of AIR Desktop Runtime, SDK and Compiler on Windows and Mac are advised to update to version 188.8.131.52.
The advisory said that Adobe Flash Player for Microsoft Edge and Internet Explorer 11 will also need a patch applied.
Meanwhile, Adobe announced the upgrade of Flash Player's extended support release from version 13 to version 18.
"This change impacts enterprise and IT customers that currently deploy Flash Player using the extended support releases available through our distribution channel," the company said.
"We will create a branch of the Flash Player code that we keep up to date with all of the latest security updates, but none of the new features or bug fixes available in our normal release branch. This allows organisations to certify and stay secure with Flash Player with minimal effort."
High-profile technology firms including Facebook and Mozilla recently threatened to stop using Flash following major security concerns stemming from the Hacking Team data leak.
Adobe thanked a number of individuals and organisations for their help in developing patches, including Project Zero, Alibaba Security and FortiGuard Labs.
However, security expert Graham Cluley recommended going further than just updating Flash. "Consider enabling click-to-play in your browser, one of the best ways to protect yourself against criminals exploiting vulnerabilities in Adobe's software," he said.
"But be warned: disabling or nobbling Flash in just your browser may not be enough to protect your computer from infection as it's perfectly possible for Flash vulnerabilities to be delivered to your PC by routes other than the web."
