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)

in memory. A local attacker can exploit this, via a
