Adobe released an update for Flash on Tuesday with patches for what it called critical issues. Like so many other flaws Adobe has already patched, those addressed in this update could let attackers remotely take control of your computer.
Adobe patches more critical Flash security flaws
Adobe says Flash version 188.8.131.52 and earlier for Mac and Windows are susceptible to the threats, as is 184.108.40.206 and earlier for ChromeOS, and 220.127.116.114 for Linux.
If you still need Flash installed on your Mac, be sure to apply this update right away. If not, consider uninstalling the software to avoid potential hacker attacks. You can check out the full list of flaws in Adobe's security bulletin.
