Descriptions

SchedMD Slurm before 20.02.7 and 20.03.x through 20.11.x before 20.11.7 allows remote code execution as SlurmUser because use of a PrologSlurmctld or EpilogSlurmctld script leads to environment mishandling.

SchedMD Slurm versiones anteriores a 20.02.7 y versiones 20.03.xa 20.11.x anteriores a 20.11.7, permite una ejecución de código remota como SlurmUser porque el uso de un script PrologSlurmctld o EpilogSlurmctld conlleva a un manejo inapropiado del entorno

USN-4781-1 fixed several vulnerabilities in Slurm. This update provides the corresponding updates for Ubuntu 14.04 ESM and Ubuntu 16.04 ESM. It was discovered that Slurm incorrectly handled certain messages between the daemon and the user. An attacker could possibly use this issue to assume control of an arbitrary file on the system. This issue only affected Ubuntu 16.04 ESM.
