Security readout for executives and security teams
CVE-2018-0256 is a denial-of-service flaw in Cisco Packet Data Network Gateway. A remote unauthenticated attacker could send a crafted peer-to-peer packet through an affected device and make the Session Manager process restart, briefly disrupting traffic. Exposure is limited to organizations running Cisco Packet Data Network Gateway where relevant peer-to-peer packets can reach or pass through the affected device. Treat this as a service-availability risk for affected Cisco gateway environments, especially where disruption to subscriber or mobile packet traffic would have business impact. Mitigation focus: Check Cisco advisory cisco-sa-20180418-pdng for affected and fixed software details.; Apply Cisco-recommended software updates or mitigations if applicable.; Restrict untrusted traffic paths to the affected peer-to-peer message processing surface..
