In the Zstandard command-line utility prior to v1.4.1, output files were created with default permissions. Correct file permissions (matching the input) would only be set at completion time. Output files could therefore be readable or writable to unintended parties.

The versions of Oracle Database Server installed on the remote host are affected by multiple vulnerabilities as referenced in the October 2023 CPU advisory.

  - Vulnerability in the Oracle Spatial and Graph (cURL) component of Oracle Database Server. Supported     versions that are affected are 19.3-19.20 and 21.3-21.11. Easily exploitable vulnerability allows low     privileged attacker having Authenticated User privilege with network access via HTTP to compromise Oracle     Spatial and Graph (cURL). Successful attacks of this vulnerability can result in unauthorized ability to     cause a hang or frequently repeatable crash (complete DOS) of Oracle Spatial and Graph (cURL).
    (CVE-2023-38039)

  - Vulnerability in the OML4Py (cryptography) component of Oracle Database Server. Supported versions that     are affected are 21.3-21.11. Difficult to exploit vulnerability allows unauthenticated attacker with     network access via HTTP to compromise OML4Py (cryptography). Successful attacks of this vulnerability can     result in unauthorized creation, deletion or modification access to critical data or all     OML4Py (cryptography) accessible data. (CVE-2022-23491)

  - Vulnerability in the PL/SQL component of Oracle Database Server. Supported versions that are affected are     19.3-19.20 and 21.3-21.11. Easily exploitable vulnerability allows high privileged attacker having Create     Session, Execute on sys.utl_http privilege with network access via Oracle Net to compromise PL/SQL.
    Successful attacks require human interaction from a person other than the attacker and while the     vulnerability is in PL/SQL, attacks may significantly impact additional products (scope change).
    Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to     some of PL/SQL accessible data as well as unauthorized read access to a subset of PL/SQL accessible data     and unauthorized ability to cause a partial denial of service (partial DOS) of PL/SQL. (CVE-2023-22071)

  - Security-in-depth update for non-exploitable vulnerabilities CVE-2020-25649, CVE-2020-36518, CVE-2021-34031,     CVE-2022-4899, CVE-2022-42003, CVE-2022-42004, CVE-2022-46908, CVE-2023-2976 and CVE-2023-35887.


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

The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5720-1 advisory.

    It was discovered that Zstandard was not properly managing file permissions when generating output files.
    A local attacker could possibly use this issue to cause a race condition and gain unauthorized access to     sensitive data.

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

According to the versions of the zstd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - In the Zstandard command-line utility prior to v1.4.1, output files were created with default permissions.
    Correct file permissions (matching the input) would only be set at completion time. Output files could     therefore be readable or writable to unintended parties. (CVE-2021-24031)

  - Beginning in v1.4.1 and prior to v1.4.9, due to an incomplete fix for CVE-2021-24031, the Zstandard     command-line utility created output files with default permissions and restricted those permissions     immediately afterwards. Output files could therefore momentarily be readable or writable to unintended     parties. (CVE-2021-24032)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
