CVE-2016-2074
Buffer overflow in lib/flow.c in ovs-vswitchd in Open vSwitch 2.2.x and 2.3.x before 2.3.3 and 2.4.x before 2.4.1 allows remote attackers to execute arbitrary code via crafted MPLS packets, as demonstrated by a long string in an ovs-appctl command.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (6.28%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
