Red Hat Security Advisory

 

Synopsis: Moderate: samba4 security update

Advisory ID: RHSA-2016:1487-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2016-1487.html

Issue date: 2016-07-26

CVE Names: CVE-2016-2119

=====================================================================

 

1. Summary:

 

An update for samba4 is now available for Red Hat Enterprise Linux 6.

 

Red Hat Product Security has rated this update as having a security impact

of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which

gives a detailed severity rating, is available for each vulnerability from

the CVE link(s) in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64

Red Hat Enterprise Linux HPC Node (v. 6) - x86_64

Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64

 

3. Description:

 

Samba is an open-source implementation of the Server Message Block (SMB) or

Common Internet File System (CIFS) protocol, which allows PC-compatible

machines to share files, printers, and other information.

 

Security Fix(es):

 

* A flaw was found in the way Samba initiated signed DCE/RPC connections. A

man-in-the-middle attacker could use this flaw to downgrade the connection

to not use signing and therefore impersonate the server. (CVE-2016-2119)

 

Red Hat would like to thank the Samba project for reporting this issue.

Upstream acknowledges Stefan Metzmacher as the original reporter.

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

After installing this update, the smb service will be restarted

automatically.
