CVE-2018-17145
Bitcoin Core 0.16.x before 0.16.2 and Bitcoin Knots 0.16.x before 0.16.2 allow remote denial of service via a flood of multiple transaction inv messages with random hashes, aka INVDoS.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.76%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
