Summary

samba security update

Details

Samba is a suite of programs for Linux and Unix to interoperate with Windows.

Security Fix(es):

A vulnerability has been found in Samba (File Transfer Software) (the affected version is unknown) and classified as critical.The CWE definition for the vulnerability is CWE-77. The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.As an impact it is known to affect confidentiality, integrity, and availability.There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.(CVE-2025-10230)

A flaw was found in Samba, in the vfs_streams_xattr module, where uninitialized heap memory could be written into alternate data streams. This allows an authenticated user to read residual memory content that may include sensitive data, resulting in an information disclosure vulnerability.(CVE-2025-9640)

Severity

10.0 (Critical)

CVE-2025-10230 (GCVE-0-2025-10230)

Vulnerability from cvelistv5 – Published: 2025-11-07 19:42 – Updated: 2026-08-31 11:24

Title

Samba: command injection in wins server hook script

Summary

A flaw was found in Samba, in the front-end WINS hook handling: NetBIOS names from registration packets are passed to a shell without proper validation or escaping. Unsanitized NetBIOS name data from WINS registration packets are inserted into a shell command and executed by the Samba Active Directory Domain Controller’s wins hook, allowing an unauthenticated network attacker to achieve remote command execution as the Samba process.

Severity

10 (Critical)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
