Google's Project Zero team identified security issues with speculative execution in microprocessors, and Couchbase is aware of the vulnerabilities like Meltdown and Spectre, which can affect modern processors and operating systems, including Intel, AMD, and ARM. To mitigate these vulnerabilities, customers should patch their operating system with recent kernel fixes, enable patches, and update processor firmware, and Couchbase recommends consulting hardware and OS vendors for specific steps to take. Additionally, Couchbase provides recommendations on how to secure the stack depending on the environment in which it is running, including deploying fixes using normal procedures and isolating Couchbase Server on dedicated physical hardware.
