medium Nessus Plugin ID 270677

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.04 / 25.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7826-1 advisory.

 Andrew Walker discovered that Samba incorrectly initialized memory in the vfs_streams_xattr module. An authenticated attacker could possibly use this issue to obtain sensitive information. (CVE-2025-9640)

 Igor Morgenstern discovered that Samba incorrectly handled names passed to the WINS hook program. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-10230)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
