Security readout for executives and security teams
CVE-2016-6467 can let a remote unauthenticated attacker crash the Network Processing Unit process on Cisco ASR 5000 Series systems running affected StarOS releases. The business impact is availability: mobile or carrier network services using these platforms could suffer disruption if exposed IPv6 traffic reaches vulnerable processing paths. Exposure is most likely where Cisco ASR 5000 Series systems run the listed vulnerable StarOS releases and process IPv6 packet fragments from untrusted or semi-trusted networks. Treat this as a targeted availability risk for ASR 5000 environments, especially carrier or service-provider networks. Prioritize version verification and planned upgrade rather than emergency response unless local exposure or reload symptoms are present. Mitigation focus: Upgrade affected ASR 5000 StarOS deployments to a listed fixed release.; Review Cisco advisory cisco-sa-20161207-asr and CSCva84552 for environment-specific guidance.; Prioritize devices running 20.0.0, 21.0.0, or 21.0.M0.64702..
