high Nessus Plugin ID 136177

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.
