Descriptions

An issue was discovered in SchedMD Slurm 22.05.x, 23.02.x, and 23.11.x. There is Improper Enforcement of Message Integrity During Transmission in a Communication Channel. This allows attackers to modify RPC traffic in a way that bypasses message hash checks. The fixed versions are 22.05.11, 23.02.7, and 23.11.1.

Se descubrió un problema en SchedMD Slurm 22.05.x, 23.02.x y 23.11.x. Existe una aplicación inadecuada de la integridad del mensaje durante la transmisión en un canal de comunicación. Esto permite a los atacantes modificar el tráfico RPC de manera que eluda las comprobaciones de hash de mensajes. Las versiones fijas son 22.05.11, 23.02.7 y 23.11.1.

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.
