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)
