Red Hat Security Advisory

 

Synopsis: Important: samba security and bug fix update

Advisory ID: RHSA-2014:1008-01

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-1008.html

Issue date: 2014-08-05

CVE Names: CVE-2014-3560

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

 

1. Summary:

 

Updated samba packages that fix one security issue and one bug are now

available for Red Hat Enterprise Linux 7.

 

The Red Hat Security Response Team has rated this update as having

Important security impact. A Common Vulnerability Scoring System (CVSS)

base score, which gives a detailed severity rating, is available from the

CVE link in the References section.

 

2. Relevant releases/architectures:

 

Red Hat Enterprise Linux Client (v. 7) - x86_64

Red Hat Enterprise Linux Client Optional (v. 7) - x86_64

Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64

Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64

Red Hat Enterprise Linux Server (v. 7) - ppc64, s390x, x86_64

Red Hat Enterprise Linux Server Optional (v. 7) - ppc64, s390x, x86_64

Red Hat Enterprise Linux Workstation (v. 7) - x86_64

Red Hat Enterprise Linux Workstation Optional (v. 7) - 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.

 

A heap-based buffer overflow flaw was found in Samba's NetBIOS message

block daemon (nmbd). An attacker on the local network could use this flaw

to send specially crafted packets that, when processed by nmbd, could

possibly lead to arbitrary code execution with root privileges.

(CVE-2014-3560)

 

This update also fixes the following bug:

 

* Prior to this update, Samba incorrectly used the O_TRUNC flag when using

the open(2) system call to access the contents of a file that was already

opened by a different process, causing the file's previous contents to be

removed. With this update, the O_TRUNC flag is no longer used in the above

scenario, and file corruption no longer occurs. (BZ#1115490)

 

All Samba users are advised to upgrade to these updated packages, which

contain backported patches to correct these issues. After installing this

update, the smb service will be restarted automatically.

 

4. Solution:

 

Before applying this update, make sure all previously released errata

relevant to your system have been applied.

 

This update is available via the Red Hat Network. Details on how to use the

Red Hat Network to apply this update are available at

https://access.redhat.com/articles/11258

 

5. Bugs fixed (https://bugzilla.redhat.com/):

 

1115490 - Samba file corruption as a result of failed lock check

1126010 - CVE-2014-3560 samba: remote code execution in nmbd
