Descriptions

Slurm 19.05.x before 19.05.7 and 20.02.x before 20.02.3, in the rare case where Message Aggregation is enabled, allows Authentication Bypass via an Alternate Path or Channel. A race condition allows a user to launch a process as an arbitrary user.

Slurm versiones 19.05.x anteriores a la versión 19.05.7 y versiones 20.02.x anteriores a la versión 20.02.3, en el extraño caso en que Message Aggregation esté habilitada, permite una Omisión de Autenticación por medio de una ruta o canal alternativo. Una condición de carrera permite a un usuario iniciar un proceso como usuario arbitrario.

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.
