The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5067-1 advisory.

    Jakub Hrozek discovered that SSSD incorrectly handled file permissions. A local attacker could possibly     use this issue to read the sudo rules available for any user. This issue only affected Ubuntu 18.04 LTS.
    (CVE-2018-10852)

    It was discovered that SSSD incorrectly handled Group Policy Objects. When SSSD is configured with too     strict permissions causing the GPO to not be readable, SSSD will allow all authenticated users to login     instead of being denied, contrary to expectations. This issue only affected Ubuntu 18.04 LTS.
    (CVE-2018-16838)

    It was discovered that SSSD incorrectly handled users with no home directory set. When no home directory     was set, SSSD would return the root directory instead of an empty string, possibly bypassing security     measures. This issue only affected Ubuntu 18.04 LTS. (CVE-2019-3811)

    Cedric Buissart discovered that SSSD incorrectly handled the sssctl command. In certain environments, a     local user could use this issue to execute arbitrary commands and possibly escalate privileges.
    (CVE-2021-3621)

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.
