Red Hat Security Advisory

 

Synopsis: Moderate: samba4 security and bug fix update

Advisory ID: RHSA-2013:1543-02

Product: Red Hat Enterprise Linux

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-1543.html

Issue date: 2013-11-21

CVE Names: CVE-2013-4124

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

 

1. Summary:

 

Updated samba4 packages that fix one security issue and two bugs are now

available for Red Hat Enterprise Linux 6.

 

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

moderate security impact. Common Vulnerability Scoring System (CVSS) base

scores, which give detailed severity ratings, are available for each

vulnerability from the CVE links 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.

 

An integer overflow flaw was found in the way Samba handled an Extended

Attribute (EA) list provided by a client. A malicious client could send a

specially crafted EA list that triggered an overflow, causing the server to

loop and reprocess the list using an excessive amount of memory.

(CVE-2013-4124)

 

Note: This issue did not affect the default configuration of the

Samba server.

 

This update fixes the following bugs:

 

* When Samba was installed in the build root directory, the RPM target

might not have existed. Consequently, the find-debuginfo.sh script did not

create symbolic links for the libwbclient.so.debug module associated with

the target. With this update, the paths to the symbolic links are relative

so that the symbolic links are now created correctly. (BZ#882338)

 

* Previously, the samba4 packages were missing a dependency for the

libreplace.so module which could lead to installation failures. With this

update, the missing dependency has been added to the dependency list of the

samba4 packages and installation now proceeds as expected. (BZ#911264)

 

All samba4 users are advised to upgrade to these updated packages, which

contain a backported patch to correct these issues.

 

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/site/articles/11258

 

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

 

911264 - libreplace.so => not found

984401 - CVE-2013-4124 samba: DoS via integer overflow when reading an EA list
