Synopsis

The remote Windows host is affected multiple elevation of privilege vulnerabilities.

Description

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

- An elevation of privilege vulnerability exists in the Windows Kernel API due to improper enforcement of permissions. A local attacker can exploit this, via a specially crafted application, to run processes in an elevated context. (CVE-2017-0050)

- An elevation of privilege vulnerability exists in the Windows Transaction Manager due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to run processes in an elevated context. (CVE-2017-0101)

- An elevation of privilege vulnerability exists due to a failure to check the length of a buffer prior to copying memory. A local attacker can exploit this, by copying a file to a shared folder or drive, to gain elevated privileges. (CVE-2017-0102)

- An elevation of privilege vulnerability exists in the Windows Kernel API due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to gain elevated privileges. (CVE-2017-0103)

Solution

Microsoft has released a set of patches for Windows Vista, 2008, 7, 2008 R2, 2012, 8.1, RT 8.1, 2012 R2, 10, and 2016.
