Our friends over at VMware have released their first security bulletin of the year.  The vulnerability is a privilege escalation issue in VMware Tools in Windows guests.  Affected products include ESXi, Workstation (versions prior to 11.1.2, version 12 is not affected), Player (prior to 7.1.2), and Fusion (prior to 7.1.2, version 8 is not affected).  This is not a guest escape and does not impact the host OS.
