Alpine: multiple ldb packages, multiple samba packages, pam-winbind: security update to 4.21.9-r0

critical Tenable Cloud Security Plugin ID 436016

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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)

 - 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. (CVE-2025-10230)
