Synopsis

The remote Red Hat host is missing a security update for samba.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2023:4328 advisory.

 Samba is an open-source implementation of the Server Message Block (SMB) protocol and the related Common Internet File System (CIFS) protocol, which allow PC-compatible machines to share files, printers, and various information.

 Security Fix(es):

 * samba: SMB2 packet signing is not enforced when server signing = required is set (CVE-2023-3347)

 For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

 Bug Fix(es):

 * The trust relationship between this workstation and the primary domain failed (BZ#2223601)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.
