Descriptions

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.

El montaje y desmontaje en util-linux y loop-aes-utils, llaman a las funciones setuid y setgid en el orden incorrecto y no comprueban los valores de retorno, lo que podría permitir a atacantes alcanzar privilegios por medio de asistentes como mount.nfs.

Ludwig Nussel discovered that the check_special_mountprog() and check_special_umountprog() functions call setuid() and setgid() in the wrong order and do not check the return values, which can lead to privileges being dropped improperly. Versions less than 2.12r-r8 are affected.
