Descriptions
.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".
.NET Core 1.0, .NET Core 1.1, NET Core 2.0 y PowerShell Core 6.0.0 permiten una vulnerabilidad de denegación de servicio (DoS) debido a la forma en la que se gestionan las peticiones especialmente manipuladas. Esto también se conoce como ".NET Core Denial of Service Vulnerability".
It was found that string comparisons in .NET Core did not use a secure hashing algorithm. This could allow an attacker to predict string hashes and cause a denial of service by intentionally creating collisions thus forcing long look up times.
