CVE-2016-1453
Buffer overflow in the Overlay Transport Virtualization (OTV) GRE feature in Cisco NX-OS 5.0 through 7.3 on Nexus 7000 and 7700 devices allows remote attackers to execute arbitrary code via long parameters in a packet header, aka Bug ID CSCuy95701.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (8.07%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
