What to do

Check whether you run it. Look for Java Runtime Environment (JRE) in your asset inventory, including appliances and cloud images. Stack check lists every exploited Oracle CVE at once.
Apply the fix. Apply updates per vendor instructions.
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 1 Apr 2010.
Get told next time. Email alerts when CISA adds a CVE for Oracle.
