Amazon Linux 2023 : libnetapi, libnetapi-devel, libsmbclient (ALAS2023-2023-206)

high Nessus Plugin ID 176912

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-206 advisory.

An information leak vulnerability was discovered in Samba's LDAP server. Due to missing access control checks, an authenticated but unprivileged attacker could discover the names and preserved attributes of deleted objects in the LDAP store. (CVE-2018-14628)

A user with sufficient privileges to create a computer account, such as a user granted CreateChild permissions for computer objects, may potentially set arbitrary values on security-sensitive attributes of specific objects stored in Active Directory (AD). (CVE-2020-25720)

Samba AD DC dnsHostname attribute can be deleted by unprivileged authenticated users. (CVE-2023-0225)

Access controlled AD LDAP attributes can be discovered (CVE-2023-0614)

Samba AD DC admin tool samba-tool sends passwords in cleartext (CVE-2023-0922)

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

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

Solution

Run 'dnf update samba --releasever 2023.0.20230607' to update your system.
