Summary
Cisco patched ten vulnerabilities, including a critical root-level remote code execution flaw in Nexus 9000 switches and multiple memory safety issues in IOS XR software.
Take Action:
If you run Cisco Nexus 9000 switches or IOS XR routers, make sure the management and control interfaces are not reachable from the internet and only accessible from trusted networks. Check your Nexus models with "show module" and block TCP ports 43210 and 43211 with access control lists until you can patch. Apply Cisco's Software Maintenance Updates (SMUs) for IOS XR and the fixed Nexus software as soon as possible.
