** Description changed:

  The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel
  through 4.3.3 attempts to merge distinct setattr operations, which
  allows local users to bypass intended access restrictions and modify the
  attributes of arbitrary overlay files via a crafted application.

Bug description:
  The ovl_setattr function in fs/overlayfs/inode.c in the Linux kernel
  through 4.3.3 attempts to merge distinct setattr operations, which
  allows local users to bypass intended access restrictions and modify
  the attributes of arbitrary overlay files via a crafted application.

  Break-Fix: - acff81ec2c79492b180fade3c2894425cd35a545
