Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing a security update KB3211308. It is, therefore, affected by multiple vulnerabilities:

(CVE-2017-0163, CVE-2017-0180)

- Multiple information disclosure vulnerabilities exist in Windows Hyper-V Network Switch due to improper validation of user-supplied input. A guest attacker can exploit these to disclose sensitive information on the host server. (CVE-2017-0168)
