Descriptions

An issue was discovered in SchedMD Slurm 22.05.x and 23.02.x. There is Incorrect Access Control: an attacker can modified their extended group list that is used with the sbcast subsystem, and open files with an unauthorized set of extended groups. The fixed versions are 22.05.11 and 23.02.7.

Se descubrió un problema en SchedMD Slurm 22.05.x y 23.02.x. Hay un control de acceso incorrecto: un atacante puede modificar su lista de grupos extendidos que se usa con el subsistema sbcast y abrir archivos con un conjunto no autorizado de grupos extendidos. Las versiones fijas son 22.05.11 y 23.02.7.

This update for slurm_20_11 fixes the following issues. Prevent filesystem race conditions that could let an attacker take control of an arbitrary file, or remove entire directories' contents. Prevent message extension attacks that could bypass the message hash. Prevent NULL pointer dereference on 'size_valp' overflow. Prevent double-xfree on error in '_unpack_node_reg_resp'. Prevent modified 'sbcast' RPCs from opening a file with the wrong group permissions. Add missing service file for slurmrestd. Fixed slurm upgrading to incompatible versions.
