Uncontrolled resource consumption in ASP.NET Core allows an unauthorized attacker to deny service over a network.

A tampering vulnerability exists when .NET Core improperly handles specially crafted files. An attacker who successfully exploited this vulnerability could write arbitrary files and directories to certain locations on a vulnerable system. However, an attacker would have limited control over the destination of the files and directories. To exploit the vulnerability, an attacker must send a specially crafted file to a vulnerable system. The security update fixes the vulnerability by ensuring .NET Core properly handles files.

Heap-based buffer overflow in .NET allows an unauthorized attacker to elevate privileges locally.

Stack-based buffer overflow in .NET and Visual Studio allows an unauthorized attacker to deny service over a network.
