Microsoft .net vulnerabilities

Origin validation error in .NET allows an unauthorized attacker to disclose information over a network.

Improper encoding or escaping of output in .NET allows an authorized attacker to perform spoofing over a network.

Improper link resolution before file access ('link following') in .NET allows an authorized attacker to perform tampering locally.

Improper link resolution before file access ('link following') in .NET allows an unauthorized attacker to perform tampering locally.

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.
