Vulnerability from variot
.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". Microsoft .NET is prone to a denial-of-service vulnerability. Successful exploits will attackers to cause performance to degrade resulting in a denial of service condition. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
