An incorrect locking fix caused a\nregression that broke graphics displays for Ubuntu 14.04 LTS guests\nrunning the Ubuntu 14.10 backport kernel within VMWare virtual\nmachines. This update fixes the problem.\n\nWe apologize for the inconvenience.\n\nOriginal advisory details:\n\n halfdog discovered that OverlayFS, when mounting on top of a FUSE mount,\n incorrectly propagated file attributes, including setuid.
