The Microsoft .NET Framework installation on the remote host is missing security updates. It is, therefore, affected by multiple vulnerabilities :

  - A denial of service vulnerability exists when .NET Core     or .NET Framework improperly handles web requests. An     attacker who successfully exploited this vulnerability     could cause a denial of service against a .NET Core or     .NET Framework web application. The vulnerability can be     exploited remotely, without authentication. A remote     unauthenticated attacker could exploit this     vulnerability by issuing specially crafted requests to     the .NET Core or .NET Framework application. The update     addresses the vulnerability by correcting how the .NET     Core or .NET Framework web application handles web     requests. (CVE-2020-1108)

  - An elevation of privilege vulnerability exists in .NET     Framework which could allow an attacker to elevate their     privilege level.  (CVE-2020-1066)

    The security update addresses the vulnerability by     correcting how the Windows GDI component handles objects     in memory. (CVE-2020-0963, CVE-2020-1179)

  - A remote code execution vulnerability exists when     Internet Explorer improperly accesses objects in memory.
    The vulnerability could corrupt memory in such a way     that an attacker could execute arbitrary code in the     context of the current user. An attacker who     successfully exploited the vulnerability could gain the     same user rights as the current user.  (CVE-2020-1062,     CVE-2020-1092)

  - An elevation of privilege vulnerability exists in     Windows Installer because of the way Windows Installer     handles certain filesystem operations.  (CVE-2020-1078)

  - A remote code execution vulnerability exists in the way     that the MSHTML engine improperly validates input. An     attacker could execute arbitrary code in the context of     the current user.  (CVE-2020-1064)

  - A remote code execution vulnerability exists in the way     that Microsoft Graphics Components handle objects in     memory. An attacker who successfully exploited the     vulnerability could execute arbitrary code on a target     system.  (CVE-2020-1153)

  - An elevation of privilege vulnerability exists in     Windows when the Windows kernel-mode driver fails to     properly handle objects in memory.
