VMware Fusion (11.x before 11.5.5), VMware Remote Console for Mac (11.x and prior before 11.2.0 ) and Horizon Client for Mac (5.x and prior before 5.4.3) contain a privilege escalation vulnerability due to improper XPC Client validation. Successful exploitation of this issue may allow attackers with normal user privileges to escalate their privileges to root on the system where Fusion, VMware Remote Console for Mac or Horizon Client for Mac is installed.
