What to do

  1. Check whether you run it. Look for OpenSSL in your asset inventory, including appliances and cloud images. Stack check lists every exploited OpenSSL 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 7 Apr 2014.
  4. Get told next time. Email alerts when CISA adds a CVE for OpenSSL.
