  "statement" : "On Red Hat Enterprise Linux, by default, mount.cifs is not provided with the setuid bit enabled. If a user has turned on the setuid bit (via chmod +s /sbin/mount.cifs), they would be affected by this issue, and can work around the problem by removing the setuid bit.                                                                            \nRed Hat Enterprise Linux 3 does not provide the mount.cifs program.",
