According to the versions of the krb5 packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

  - ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before     1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon     crash. This occurs because a return value is not properly managed in a certain situation. (CVE-2021-36222)

  - The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has     a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.
    (CVE-2021-37750)

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.

The remote NewStart CGSL host, running version MAIN 5.04, has krb5 packages installed that are affected by multiple vulnerabilities:

  - The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has     a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.
    (CVE-2021-37750)

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that     may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit     platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other     platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.
    (CVE-2022-42898)

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

The remote host is affected by the vulnerability described in GLSA-202405-11 (MIT krb5: Multiple Vulnerabilities)

  - ec_verify in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before     1.18.4 and 1.19.x before 1.19.2 allows remote attackers to cause a NULL pointer dereference and daemon     crash. This occurs because a return value is not properly managed in a certain situation. (CVE-2021-36222)

  - The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) before 1.18.5 and 1.19.x before 1.19.3 has     a NULL pointer dereference in kdc/do_tgs_req.c via a FAST inner body that lacks a server field.
    (CVE-2021-37750)

  - PAC parsing in MIT Kerberos 5 (aka krb5) before 1.19.4 and 1.20.x before 1.20.1 has integer overflows that     may lead to remote code execution (in KDC, kadmind, or a GSS or Kerberos application server) on 32-bit     platforms (which have a resultant heap-based buffer overflow), and cause a denial of service on other     platforms. This occurs in krb5_pac_parse in lib/krb5/krb/pac.c. Heimdal before 7.7.1 has a similar bug.
    (CVE-2022-42898)

  - lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an     uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because
    _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array     count. (CVE-2023-36054)

  - kdc/do_tgs_req.c in MIT Kerberos 5 (aka krb5) 1.21 before 1.21.2 has a double free that is reachable if an     authenticated user can trigger an authorization-data handling failure. Incorrect data is copied from one     ticket to another. (CVE-2023-39975)

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

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

  - Vulnerability in the Oracle Database - Machine Learning for Python (Python) component of Oracle Database     Server. The supported version that is affected is 21c. Easily exploitable vulnerability allows low     privileged attacker having Database User privilege with network access via Oracle Net to compromise Oracle     Database - Machine Learning for Python (Python). Successful attacks of this vulnerability can result in     unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Database -     Machine Learning for Python (Python). (CVE-2021-3737)

  - Vulnerability in the Oracle Database RDBMS Security component of Oracle Database Server. Supported     versions that are affected are 19c and 21c. Easily exploitable vulnerability allows low privileged     attacker having Create Session privilege with network access via Oracle Net to compromise Oracle Database     RDBMS Security. Successful attacks require human interaction from a person other than the attacker.
    Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification     access to critical data or all Oracle Database RDBMS Security accessible data as well as unauthorized read     access to a subset of Oracle Database RDBMS Security accessible data. (CVE-2023-21829)

  - Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are     19c and 21c. Easily exploitable vulnerability allows low privileged attacker having Create Procedure     privilege with network access via Oracle Net to compromise Java VM. Successful attacks of this     vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of     Java VM. (CVE-2022-39429)

  - Vulnerability in the Oracle Database Data Redaction component of Oracle Database Server. Supported     versions that are affected are 19c and 21c. Easily exploitable vulnerability allows low privileged     attacker having Create Session privilege with network access via Oracle Net to compromise Oracle Database     Data Redaction. Successful attacks of this vulnerability can result in unauthorized read access to a     subset of Oracle Database Data Redaction accessible data. (CVE-2023-21827)
