## Notes

### [mdeslaur](https://launchpad.net/~mdeslaur)

mount.vmhgfs not suid root in Debian and Ubuntu, negligible
security impact. Upstream commit removes vmhgfs in favour of
hgfs-fuse.
Since this has no security impact on Ubuntu, and there is no
upstream fix for the issue, we will not be fixing this in
stable releases.
