                   Red Hat Security Advisory

Synopsis:          Moderate: samba security update
Advisory ID:       RHSA-2014:0305-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-0305.html
Issue date:        2014-03-17
CVE Names:         CVE-2013-0213 CVE-2013-0214 CVE-2013-4124 
=====================================================================

1. Summary:

Updated samba packages that fix three security issues are now available for
Red Hat Enterprise Linux 5.

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:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - 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.

It was discovered that the Samba Web Administration Tool (SWAT) did not
protect against being opened in a web page frame. A remote attacker could
possibly use this flaw to conduct a clickjacking attack against SWAT users
or users with an active SWAT session. (CVE-2013-0213)

A flaw was found in the Cross-Site Request Forgery (CSRF) protection
mechanism implemented in SWAT. An attacker with the knowledge of a victim's
password could use this flaw to bypass CSRF protections and conduct a CSRF
attack against the victim SWAT user. (CVE-2013-0214)

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.

Red Hat would like to thank the Samba project for reporting CVE-2013-0213
and CVE-2013-0214. Upstream acknowledges Jann Horn as the original reporter
of CVE-2013-0213 and CVE-2013-0214.

All users of Samba 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/site/articles/11258

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

905700 - CVE-2013-0213 samba: clickjacking vulnerability in SWAT
905704 - CVE-2013-0214 samba: cross-site request forgery vulnerability in SWAT
984401 - CVE-2013-4124 samba: DoS via integer overflow when reading an EA list
