Security readout for executives and security teams

This Cisco IOS and IOS XE issue can let a remote attacker trigger a device reload, causing a denial of service. The described path requires leveraging an MSDP peer relationship, so exposure is most relevant to networks using multicast routing features, not every Cisco deployment. Likely exposed systems are Cisco IOS or IOS XE devices in the named version ranges that participate in MSDP peer relationships and process multicast NTP traffic. The bundle does not provide CPEs or a complete affected-products table. Treat this as a maintenance-priority outage risk for multicast-enabled Cisco routing infrastructure. It is not reported here as actively exploited, but affected core devices could reload unexpectedly if exposed through the described peer relationship path. Mitigation focus: Check Cisco advisory cisco-sa-20130925-ntp for fixed software or official workarounds.; Inventory Cisco IOS and IOS XE devices in the named affected version ranges.; Review whether MSDP peer relationships are required on affected devices..
