CVE-2014-2113: Cisco IOS 15.1 through 15.3 and IOS XE 3.3 and 3.5 before 3.5.2E; 3.7 before 3.7.5S; and 3.8, 3.9, and 3.10...

Security readout for executives and security teams

CVE-2014-2113 is a Cisco IOS and IOS XE denial-of-service issue. A malformed IPv6 packet can consume I/O memory and trigger a device reload. For executives, the business risk is network disruption on affected routing or switching infrastructure, not data theft based on the provided sources. Exposure is most likely where affected Cisco IOS or IOS XE devices process IPv6 traffic from untrusted or broad network paths. The provided source bundle does not name specific hardware models, configurations, or required IPv6 features beyond malformed IPv6 packet handling. Handle as a targeted network resilience issue. Prioritize critical Cisco infrastructure where unexpected reloads would disrupt operations, especially internet edge, WAN, data-center, and remote access paths. Urgency increases if affected devices are still running old IOS or IOS XE releases. Mitigation focus: Review Cisco advisory cisco-sa-20140326-ipv6 for fixed software guidance.; Upgrade IOS XE to applicable fixed releases: 3.5.2E, 3.7.5S, or 3.10.2S or later.; For IOS 15.1 through 15.3, confirm Cisco-recommended fixed software before upgrading..
