Red Hat Security Advisory
Synopsis: Moderate: samba security, bug fix, and enhancement update
Advisory ID: RHSA-2017:2778-01
Product: Red Hat Gluster Storage
Advisory URL: https://access.redhat.com/errata/RHSA-2017:2778
Issue date: 2017-09-21
CVE Names: CVE-2017-2619 CVE-2017-9461
=====================================================================
1. Summary:
An update for samba is now available for Red Hat Gluster Storage 3.3 for
RHEL 6.
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.
2. Relevant releases/architectures:
Red Hat Gluster 3.3 Samba on RHEL-6 - noarch, x86_64
3. Description:
Samba is an open-source implementation of the Server Message Block (SMB)
protocol and the related Common Internet File System (CIFS) protocol, which
allow PC-compatible machines to share files, printers, and various
information.
Security Fix(es):
* A race condition was found in samba server. A malicious samba client
could use this flaw to access files and directories in areas of the server
file system not exported under the share definitions. (CVE-2017-2619)
* A flaw was found in the way Samba handled dangling symlinks. An
authenticated malicious Samba client could use this flaw to cause the smbd
daemon to enter an infinite loop and use an excessive amount of CPU and
memory. (CVE-2017-9461)
Red Hat would like to thank the Samba project for reporting CVE-2017-2619.
Upstream acknowledges Jann Horn (Google) as the original reporter of
CVE-2017-2619.
Bug Fix(es):
* In the samba configuration, by default the 'posix locking' is enabled and
'stat cache' is disabled. Enabling 'posix locking' sends the file lock
request to the bricks too, and disabling 'stat cache' blocks samba to cache
certain information at the samba layer. This led to decrease in performance
of SMB access of Red Hat Gluster Storage volumes
As a fix, the following two options are included in the samba configuration
file:
posix locking = No
stat cache = Yes
Due to this, a slight improvement in the performance is observed.
(BZ#1436265)
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing this update, the smb service will be restarted
automatically.
5. Bugs fixed (https://bugzilla.redhat.com/):
1334397 - Samba [RHEL6] : Upon smbd crash the log displays core dump path as /var/log/samba/cores/smbd but in actual the core is dumped in /var/log/cores
1426663 - [RHEL6] Samba: Yum update for Samba will fail due to higher versions in RHEL 6
1429472 - CVE-2017-2619 samba: symlink race permits opening files outside share directory
1436265 - Smb.conf options for performance improvements [RHEL6]
1444028 - [SAMBA-RHEL6]Unable to start smbd in RHEL6 as /run/smbd.pid does not exist
1459464 - CVE-2017-9461 samba: fd_open_atomic infinite loop due to wrong handling of dangling symlinks

* A race condition was found in samba server. A malicious samba client
could use this flaw to access files and directories in areas of the server
file system not exported under the share definitions. (CVE-2017-2619)
* It was found that samba did not enforce "SMB signing" when certain
configuration options were enabled. A remote attacker could launch a
man-in-the-middle attack and retrieve information in plain-text.
(CVE-2017-12150)
* An information leak flaw was found in the way SMB1 protocol was
implemented by Samba. A malicious client could use this flaw to dump server
memory contents to a file on the samba share or to a shared printer, though
the exact area of server memory cannot be controlled by the attacker.
(CVE-2017-12163)
Red Hat would like to thank the Samba project for reporting CVE-2017-2619

3. Description:
Samba is an open-source implementation of the Server Message Block (SMB)
protocol and the related Common Internet File System (CIFS) protocol, which
allow PC-compatible machines to share files, printers, and various
information.
Security Fix(es):
* It was found that samba did not enforce "SMB signing" when certain
configuration options were enabled. A remote attacker could launch a
man-in-the-middle attack and retrieve information in plain-text.
(CVE-2017-12150)
* A flaw was found in the way samba client used encryption with the max
protocol set as SMB3. The connection could lose the requirement for signing
and encrypting to any DFS redirects, allowing an attacker to read or alter
the contents of the connection via a man-in-the-middle attack.
(CVE-2017-12151)
* An information leak flaw was found in the way SMB1 protocol was
implemented by Samba. A malicious client could use this flaw to dump server
memory contents to a file on the samba share or to a shared printer, though
the exact area of server memory cannot be controlled by the attacker.
(CVE-2017-12163)
Red Hat would like to thank the Samba project for reporting CVE-2017-12150
and CVE-2017-12151 and Yihan Lian and Zhibin Hu (Qihoo 360 GearTeam),
Stefan Metzmacher (SerNet), and Jeremy Allison (Google) for reporting
CVE-2017-12163. Upstream acknowledges Stefan Metzmacher (SerNet) as the
original reporter of CVE-2017-12150 and CVE-2017-12151.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing this update, the smb service will be restarted
automatically.
5. Bugs fixed (https://bugzilla.redhat.com/):
1488197 - CVE-2017-12151 samba: SMB2 connections don't keep encryption across DFS redirects
1488400 - CVE-2017-12150 samba: Some code path don't enforce smb signing, when they should
1491206 - CVE-2017-12163 Samba: Server memory information leak over SMB1

Red Hat Security Advisory
Synopsis: Moderate: samba4 security update
Advisory ID: RHSA-2017:2791-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:2791
Issue date: 2017-09-21
CVE Names: CVE-2017-12150 CVE-2017-12163
=====================================================================
1. Summary:
An update for samba4 is now available for Red Hat Enterprise Linux 6.
Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) 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.
Security Fix(es):
* It was found that samba did not enforce "SMB signing" when certain
configuration options were enabled. A remote attacker could launch a
man-in-the-middle attack and retrieve information in plain-text.
(CVE-2017-12150)
* An information leak flaw was found in the way SMB1 protocol was
implemented by Samba. A malicious client could use this flaw to dump server
memory contents to a file on the samba share or to a shared printer, though
the exact area of server memory cannot be controlled by the attacker.
(CVE-2017-12163)
Red Hat would like to thank the Samba project for reporting CVE-2017-12150
and Yihan Lian and Zhibin Hu (Qihoo 360 GearTeam), Stefan Metzmacher
(SerNet), and Jeremy Allison (Google) for reporting CVE-2017-12163.
Upstream acknowledges Stefan Metzmacher (SerNet) as the original reporter
of CVE-2017-12150.
4. Solution:
For details on how to apply this update, which includes the changes
described in this advisory, refer to:
https://access.redhat.com/articles/11258
After installing this update, the smb service will be restarted
automatically.
5. Bugs fixed (https://bugzilla.redhat.com/):
1488400 - CVE-2017-12150 samba: Some code path don't enforce smb signing, when they should
1491206 - CVE-2017-12163 Samba: Server memory information leak over SMB1
