Topic

Updated samba packages that fix one security issue are now available for
Red Hat Storage 3.

Red Hat Product Security has rated this update as having Critical 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.

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 uninitialized pointer use flaw was found in the Samba daemon (smbd).
A malicious Samba client could send specially crafted netlogon packets
that, when processed by smbd, could potentially lead to arbitrary code
execution with the privileges of the user running smbd (by default, the
root user). (CVE-2015-0240)

For additional information about this flaw, see the Knowledgebase article
at https://access.redhat.com/articles/1346913

Red Hat would like to thank the Samba project for reporting this issue.
Upstream acknowledges Richard van Eeden of Microsoft Vulnerability Research
as the original reporter of this issue.

All Samba users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing this
update, the smb service will be restarted automatically.

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
