"The following security issues were fixed :

  - FUSE allowed 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. (CVE-2010-3879)

  - Avoid mounting a directory including evaluation of
    symlinks, which might have allowed local attackers to
    mount filesystems anywhere in the system.
    (CVE-2011-0541)

  - Avoid symlink attacks on the mount point written in the
    mtab file. Four bugs were fixed:. (CVE-2011-0543)

  - fixed retrying nfs mounts on rpc timeouts

  - allow seperate control of the internet protocol uses by
    rpc.mount seperately of the protocol used by nfs.

  - Fixed locking in libuuid/uuid to avoid duplicate uuids.

  - mkswap bad block check marked every block bad in O(n!)
    time on a good device New features were implemented :

  - mount now has --fake and --no-canonicalize options,
    required for the symlink security fixes. These were
    backported from mainline.

  - mount can now auto-detect and differentiate between
    squashfs3 and squashfs (v4) filesystems, allowing
    backward compatibility to the SUSE Linux Enterprise 11
    GA codebase."
