What it is

Adobe Reader and Acrobat on Windows allow attackers to bypass a sandbox protection mechanism, and consequently execute native code in a privileged context.

What to do

1. Check whether you run it. Look for Reader and Acrobat in your asset inventory, including appliances and cloud images. Stack check lists every exploited Adobe CVE at once.
2. Apply the fix. Apply updates per vendor instructions.
3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 12 Aug 2014.
4. Get told next time. Email alerts when CISA adds a CVE for Adobe.
