Normally on a proper setup Linux/Unix Box external Media (floppy, Zip, CD) all
are mounted without permission to execute.  You have to change your mount
options. When my CD is mounted "mount" shows:
  /dev/scd1 on /mnt/cdrom2 type iso9660 (ro,noexec,nosuid,nodev,user=koloska)

noexec, nosuid and nodev are important for security.  Otherwise some user can
mount a CD with some suid root programms and ...

a) mount it by hand:
       mount -t iso9660 /dev/scd0 /mnd/cdrom
   without any options there only is a message that a CD can't be written ...

b) change your /etc/fstab so that a normal user can mount a CD but have the
   right to execute:
       /dev/scd0    /mnt/cdrom    iso9660   ro,noauto,user,exec,defaults   1  0
   'user' is the option that implies noexec, nosuid, nodev that has to be
   explicitly overwritten

Hope that helps
