'-r' option could allow flags in /etc/fstab to be improperly dropped
on user-mountable volumes, allowing a user to gain root privileges.

Here are the details from the Slackware 10.1 ChangeLog:
+--------------------------+
patches/packages/util-linux-2.12p-i486-2.tgz: Patched an issue with
 umount where if the umount failed when the '-r' option was used, the
 filesystem would be remounted read-only but without any extra flags
 specified in /etc/fstab. This could allow an ordinary user able to
 mount a floppy or CD (but with nosuid, noexec, nodev, etc in
 /etc/fstab) to run a setuid binary from removable media and gain
 root privileges.
