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
