RHSA-2023:7464 - Moderate: samba security update


Synopsis

Moderate: samba security update

Type/Severity

Security Advisory Moderate

Topic

An update for samba is now available for Red Hat Enterprise Linux 8.8 Extended Update Support.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Description

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: smbd allows client access to unix domain sockets on the file system as root (CVE-2023-3961)

  • samba: SMB clients can truncate files with read-only permissions (CVE-2023-4091)

  • samba: "rpcecho" development server allows denial of service via sleep() call on AD DC (CVE-2023-42669)

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.

Solution
