It is very important that all users of Adobe Flash ensure they have the latest versions installed on all workstations — this one is pretty gnarly and will likely be getting a lot of attention in short order.
The relevant CVEs ((Common Vulnerabilities and Exposures reference number used by researchers and vendors)) are:
And from Adobe’s release, the list of vulnerable versions is quite broad:
Affected software versions
- Adobe Flash Player 184.108.40.206 and earlier versions for Windows and Macintosh
- Adobe Flash Player 220.127.116.116 and earlier versions for Linux
- Adobe AIR 18.104.22.1680 and earlier versions for Android
- Adobe AIR 22.214.171.1240 SDK and earlier versions
- Adobe AIR 126.96.36.1990 SDK & Compiler and earlier versions
Essentially, if you didn’t download a new version of Adobe Flash today, you’re probably vulnerable.
Adobe has released security updates for Adobe Flash Player 188.8.131.52 and earlier versions for Windows and Macintosh and Adobe Flash Player 184.108.40.2066 and earlier versions for Linux.
