Samba: Mehrere Schwachstellen
WID-SEC-2023-0796 · first 30.03.2023 · updated 01.09.2026 · CVSS 8,1
What it is about
Samba ist eine Open Source Software Suite, die Druck- und Dateidienste für SMB/CIFS Clients implementiert. SUSE Linux ist eine Linux-Distribution bzw. Open Source Plattform. SUSE Manager basiert auf Spacewalk, welche die Codebase vom Red Hat Satellite Server nutzt und ermöglicht ein zentrale Systemmanagement von Linux-Umgebungen. Ein entfernter, authentisierter oder anonymer Angreifer kann mehrere Schwachstellen in Samba ausnutzen, um Dateien zu manipulieren und Informationen offenzulegen.
Under what conditions?
Over the network, but only with valid access (login required), for example with stolen credentials or as an insider.
What can happen in the worst case
An attacker could use the vulnerability to
- Dateien zu manipulieren
- Informationen offenzulegen
Am I affected?
Affected according to the BSI:
- Fedora Linux
- Ubuntu Linux
- SUSE Manager
- Gentoo Linux
- SUSE Linux Enterprise
- SUSE Linux Enterprise Server
- Open Source Samba <4.18.1
- Open Source Samba <4.17.7
- Open Source Samba <4.16.10
- SUSE Manager Server
- SUSE Manager Proxy
- SUSE Manager Retail Branch Server
and 2 more
The installed version is usually shown under “Help → About” or in the device’s admin interface.
What helps?

- Open Source Samba 4.18.1
- Open Source Samba 4.17.7
- Open Source Samba 4.16.10
- HPE HP-UX (CIFS) Client/Server B.04.18.01.00
