MiracleLinux 7 : samba-4.2.10-7.el7 (AXSA:2016-578:06)

high Nessus Plugin ID 291547

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 7 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2016-578:06 advisory.

Samba is the standard Windows interoperability suite of programs for Linux and Unix.
Security issues fixed with this release:
CVE-2016-2119 libcli/smb/smbXcli_base.c in Samba 4.x before 4.2.14, 4.3.x before 4.3.11, and 4.4.x before 4.4.5 allows man-in-the-middle attackers to bypass a client-signing protection mechanism, and consequently spoof SMB2 and SMB3 servers, via the (1) SMB2_SESSION_FLAG_IS_GUEST or (2) SMB2_SESSION_FLAG_IS_NULL flag.
Fixed bugs:
* Previously, the net command in some cases failed to join the client to Active Directory (AD) because the permissions setting prevented modification of the supported Kerberos encryption type LDAP attribute.
With this update, Samba has been fixed to allow joining an AD domain as a user. In addition, Samba now uses the machine account credentials to set up the Kerberos encryption types within AD for the joined machine. As a result, using net to join a domain now works more reliably.
* Previously, the idmap_hash module worked incorrectly when it was used together with other modules. As a consequence, user and group IDs were not mapped properly. A patch has been applied to skip already configured modules. Now, the hash module can be used as the default idmap configuration back end and IDs are resolved correctly.

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

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

Solution

Update the affected packages.
