Recommended defensive actions

  • Inventory systems that have Oracle Java SE installed, including legacy endpoints and servers.
  • Apply Oracle’s vendor updates and follow Oracle’s remediation guidance as soon as possible.
  • Prioritize remediation on internet-facing, high-value, and widely deployed systems.
  • Verify that affected systems are actually updated and that older Java components have been removed or disabled where not needed.
  • Track any lingering installations separately so they do not remain unpatched because of application dependencies.
