The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

  • An arbitrary code execution vulnerability exists in Hyper-V due to a failure to properly validate input from an authenticated user on a guest operating system. An attacker can exploit this, via a crafted application on the guest operating system, to execute arbitrary code on the host operating system. (CVE-2016-0088)

  • Multiple information disclosure vulnerabilities exists in Hyper-V due to a failure to properly validate input from an authenticated user on a guest operating system.
    An attacker can exploit this, via a crafted application on the guest operating system, to disclose memory information on the host operating system.
    (CVE-2016-0089, CVE-2016-0090)

Note that users who have not enabled the Hyper-V role are not affected by these vulnerabilities.
