Virtualization 6.x prior to 6.4.1953.  It is, therefore, affected by a
local privilege escalation vulnerability due to a failure to sanitize
user-supplied input.  An attacker could potentially exploit this
vulnerability to run arbitrary code with SYSTEM level privileges. 

Note that the vulnerability is only exploitable if at least one virtual
application layer is activated/enabled."
