Ubuntu 23.10 : Samba vulnerabilities (USN-6425-3)

medium Nessus Plugin ID 183272

Language:

Synopsis

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

Description

The remote Ubuntu 23.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6425-3 advisory.

 USN-6425-1 fixed vulnerabilities in Samba. This update provides the corresponding updates for Ubuntu 23.10.

 Original advisory details:

 Sri Nagasubramanian discovered that the Samba acl_xattr VFS module

 incorrectly handled read-only files. When Samba is configured to ignore

 system ACLs, a remote attacker could possibly use this issue to truncate

 read-only files. (CVE-2023-4091)

 Andrew Bartlett discovered that Samba incorrectly handled the DirSync

 control. A remote attacker with an RODC DC account could possibly use this

 issue to obtain all domain secrets. (CVE-2023-4154)

 Andrew Bartlett discovered that Samba incorrectly handled the rpcecho

 development server. A remote attacker could possibly use this issue to

 cause Samba to stop responding, resulting in a denial of service.

 (CVE-2023-42669)

 Kirin van der Veer discovered that Samba incorrectly handled certain RPC

 service listeners. A remote attacker could possibly use this issue to cause

 Samba to start multiple incompatible RPC listeners, resulting in a denial

 of service. This issue only affected Ubuntu 22.04 LTS, and Ubuntu 23.04.

 (CVE-2023-42670)

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
