CVE-2017-10620
This may allow a man-in-the-middle attacker to inject bogus signatures to cause service disruptions or make the device not detect certain types of attacks.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
