CVE-2016-6392
Cisco IOS 12.2 and 15.0 through 15.3 and IOS XE 3.1 through 3.9 allow remote attackers to cause a denial of service (device restart) via a crafted IPv4 Multicast Source Discovery Protocol (MSDP) Source-Active (SA) message, aka Bug ID CSCud36767.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.59%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
