Slurm before 19.05.8 and 20.x before 20.02.6 exposes Sensitive Information to an Unauthorized Actor because xauth for X11 magic cookies is affected by a race condition in a read operation on the /proc filesystem.

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4781-1 advisory.

    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. (CVE-2016-10030)

    It was discovered that Slurm mishandled SPANK environment variables. An attacker could possibly use this     issue to gain elevated privileges. This issue only affected Ubuntu 16.04 ESM. (CVE-2017-15566)

    It was discovered that Slurm mishandled certain SQL queries. A local attacker could use this issue to gain     elevated privileges. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM and Ubuntu 18.04 ESM.
    (CVE-2018-7033)

    It was discovered that Slurm mishandled user names and group ids. A local attacker could use this issue to     gain administrative privileges. This issue only affected Ubuntu 14.04 ESM and Ubuntu 18.04 ESM.
    (CVE-2018-10995)

    It was discovered that Slurm mishandled 23-bit systems. A local attacker could use this to gain     administrative privileges. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM and Ubuntu 18.04     ESM. (CVE-2019-6438)

    It was discovered that Slurm incorrectly handled certain inputs when Message Aggregation is enabled. An     attacker could possibly use this issue to launch a process as an arbitrary user. This issue only affected     Ubuntu 16.04 ESM, Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2020-12693)

    It was discovered that Slurm incorrectly handled certain RPC inputs. An attacker could possibly use this     issue to execute arbitrary code. This issue only affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM.
    (CVE-2020-27745)

    Jonas Stare discovered that Slurm exposes sensitive information related to the X protocol. An attacker     could possibly use this issue to obtain a graphical session from an arbitrary user. This issue only     affected Ubuntu 18.04 ESM and Ubuntu 20.04 ESM. (CVE-2020-27746)

    It was discovered that Slurm incorrectly handled environment parameters. An attacker could possibly use     this issue to execute arbitrary code. (CVE-2021-31215)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple security issues were discovered in the Simple Linux Utility for Resource Management (SLURM), a cluster resource management and job scheduling system, which could result in denial of service, information disclosure or privilege escalation.
