FUSE, possibly 2.8.5 and earlier, allows local users to create mtab entries
with arbitrary pathnames, and consequently unmount any filesystem, via a
symlink attack on the parent directory of the mountpoint of a FUSE
filesystem, a different vulnerability than CVE-2010-0789.

Notes

Author	Note
mdeslaur	will also need to patch util-linux to get --no-canonicalize See novell bug for a bunch of commits, and new patches util-linux negligible (update only needed for fuse)
