Samba 4.10.x < 4.10.15 / 4.11.x < 4.11.8 / 4.12.x < 4.12.2 Multiple Vulnerabilities

high Nessus Plugin ID 136177
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Samba server is potentially affected by multiple vulnerabilities.

Description

The version of Samba running on the remote host is 4.10.x prior to 4.10.15, 4.11.x prior to 4.11.8, or 4.12.x prior to 4.12.2. It is, therefore, affected by the following vulnerabilities :

- A flaw exists related to handling 'ASQ' and 'Paged Results' LDAP controls that could allow use-after-free conditions having unspecified impact. (CVE-2020-10700)

- A flaw exists related to handling deeply nested filters, un-authenticated LDAP searches, and stack memory that could allow application crashes.
(CVE-2020-10704)

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

Solution

Upgrade to Samba version 4.10.15 / 4.11.8 / 4.12.2 or later.
