Description Stefan Cornelius 2020-07-27 20:36:13 UTC 
It was discovered that ASP.NET Core did not properly handle client disconnects under all circumstances. By sending specially crafted requests to an ASP.NET Core application, a remote unauthenticated attacker could possibly exploit this flaw to consume more disk and CPU resources than necessary, possibly leading to a denial of service via resource exhaustion.
