CVE-2018-0875
.NET Core 1.0, .NET Core 1.1, NET Core 2.0 and PowerShell Core 6.0.0 allow a denial of Service vulnerability due to how specially crafted requests are handled, aka ".NET Core Denial of Service Vulnerability".
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (9.08%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
