Descriptions

A vulnerability in Intermediate System-to-Intermediate System (IS-IS) protocol packet processing of Cisco Nexus 5000, 6000, and 7000 Series Switches software could allow an unauthenticated, adjacent attacker to cause a reload of the affected device. Switches in the FabricPath domain crash because of an __inst_001__isis_fabricpath hap reset when processing a crafted link-state packet. More Information: CSCvc45002. Known Affected Releases: 7.1(3)N1(2.1) 7.1(3)N1(3.12) 7.3(2)N1(0.296) 8.0(1)S2.
