mount and umount in util-linux and loop-aes-utils call the setuid and setgid functions in the wrong order and do not check the return values, which might allow attackers to gain privileges via helpers such as mount.nfs.
script command in the util-linux package before 2.11n allows local users to overwrite arbitrary files by setting a hardlink from the typescript log file to any file on the system, then having root execute the script command.
