  "description": "Parallels Desktop runs\u00A0prl_disp_service\u00A0as root. Local clients reach it on the world-writable socket\u00A0/var/run/prl_disp_service.socket.\u00A0PrlSrv_LoginLocal\u00A0accepts peer credentials. No Parallels signature. No admin group.\n\n\n\nAfter login,\u00A0PrlSrv_InstallAppliance\u00A0lets you pick the appliance folder (sVmParentPath). The daemon unpacks with one string,\u00A0tar -xf \u0022%1\u0022 -C \u0022%2\u0022, then Qt\u00A0QProcess::splitCommand\u00A0chops that string into words. A quote in the folder name closes early. The leftover text becomes extra tar flags. macOS\u00A0tar --use-compress-program=\u00A0runs the named program as root.",
