Security readout for executives and security teams

This is a Cisco IOS availability flaw. If a router has a VRF interface configured, crafted ICMPv4 traffic can wedge an interface queue and cause denial of service. Business impact is network disruption, not data theft, based on the supplied sources. Exposure is most likely on Cisco IOS routers running the named release trains with VRF interfaces enabled and reachable by ICMPv4 traffic. The bundle does not identify specific device models, fixed releases, or CPEs. Schedule remediation based on business criticality of affected routers. The main risk is service disruption on routing infrastructure, especially where VRF interfaces are exposed to untrusted ICMPv4 traffic. Mitigation focus: Review Cisco advisory cisco-sa-20150325-wedge for fixed releases or workarounds.; Inventory Cisco IOS versions 12.2, 12.4, 15.0, 15.2, and 15.3.; Identify routers with configured VRF interfaces..
