Windows Hyper-V vSMB Elevation of Privilege Vulnerability
CVE-2017-0212 is fixed in 6 products on 1 platform, first by KB4019473, released May 9, 2017. It is not reported as exploited. Patch Radar priority: High.
<p>An elevation of privilege vulnerability exists when Windows Hyper-V on a host server fails to properly validate vSMB packet data. An attacker who successfully exploited these vulnerabilities could gain elevated privileges on a target operating system.</p> <p>This vulnerability by itself does not allow arbitrary code to be run. However, this vulnerability could be used in conjunction with one or more vulnerabilities (e.g. a remote code execution vulnerability and another elevation of privilege) that could take advantage of the elevated privileges when running.</p> <p>The update addresses the vulnerabilities by correcting how Windows Hyper-V validates vSMB packet data.</p>
