A denial of service vulnerability exists when Hyper-V on a Windows Server fails to properly handle specially crafted network packets.To exploit the vulnerability, an attacker would send specially crafted network packets to the Hyper-V Server.The security update addresses the vulnerability by resolving the conditions where Hyper-V would fail to properly handle these network packets., aka 'Windows Hyper-V Denial of Service Vulnerability'.

DHCP Server Service Denial of Service Vulnerability

Windows TCP/IP Denial of Service Vulnerability

.NET and Visual Studio Denial of Service Vulnerability

When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API. However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory.
