Descriptions

Privilege escalation can occur in the SUSE useradd.c code in useradd, as distributed in the SUSE shadow package through 4.2.1-27.9.1 for SUSE Linux Enterprise 12 (SLE-12) and through 4.5-5.39 for SUSE Linux Enterprise 15 (SLE-15). Non-existing intermediate directories are created with mode 0777 during user creation. Given that they are world-writable, local attackers might use this for privilege escalation and other unspecified attacks. NOTE: this would affect non-SUSE users who took useradd.c code from a 2014-04-02 upstream pull request; however, no non-SUSE distribution is known to be affected.

Puede ocurrir un escalado de privilegios en el código SUSE useradd en useradd.c, tal y como se distribuye en el paquete SUSE shadow hasta la versión 4.2.1-27.9.1 para SUSE Linux Enterprise 12 (SLE-12) y hasta la versión 4.5-5.39 para SUSE Linux Enterprise 15 (SLE-15). Se crean directorios intermedios no existentes con modo 0777 durante la creación de usuarios. Teniendo en cuenta que son modificables por cualquier usuario, los atacantes locales podrían emplear esto para escalar privilegios y otros ataques sin especificar. NOTA: esto afectaría a otros usuarios fuera de SUSE que tomaron código de useradd.c de una petición pull ascendente el 02/04/2014; sin embargo, no se conocen distribuciones externas a SUSE afectadas.
