"Several vulnerabilities have been discovered in Samba, a SMB/CIFS
file, print, and login server for Unix. The Common Vulnerabilities and
Exposures project identifies the following issues :

  - CVE-2016-2119
    Stefan Metzmacher discovered that client-side SMB2/3
    required signing can be downgraded, allowing a
    man-in-the-middle attacker to impersonate a server being
    connected to by Samba, and return malicious results.

  - CVE-2016-2123
    Trend Micro's Zero Day Initiative and Frederic Besler
    discovered that the routine ndr_pull_dnsp_name, used to
    parse data from the Samba Active Directory ldb database,
    contains an integer overflow flaw, leading to an
    attacker-controlled memory overwrite. An authenticated
    user can take advantage of this flaw for remote
    privilege escalation.

  - CVE-2016-2125
    Simo Sorce of Red Hat discovered that the Samba client
    code always requests a forwardable ticket when using
    Kerberos authentication. A target server, which must be
    in the current or trusted domain/realm, is given a valid
    general purpose Kerberos 'Ticket Granting Ticket' (TGT),
    which can be used to fully impersonate the authenticated
    user or service.

  - CVE-2016-2126
    Volker Lendecke discovered several flaws in the Kerberos
    PAC validation. A remote, authenticated, attacker can
    cause the winbindd process to crash using a legitimate
    Kerberos ticket due to incorrect handling of the PAC
    checksum. A local service with access to the winbindd
    privileged pipe can cause winbindd to cache elevated
    access permissions."

"An update for samba is now available for Red Hat Enterprise Linux 7.

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.

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 always requested forwardable tickets when
using Kerberos authentication. A service to which Samba authenticated
using Kerberos could subsequently use the ticket to impersonate Samba
to other services or domain users. (CVE-2016-2125)

* A flaw was found in the way Samba handled PAC (Privilege Attribute
Certificate) checksums. A remote, authenticated attacker could use
this flaw to crash the winbindd process. (CVE-2016-2126)

* 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)

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."

"An update for samba is now available for Red Hat Gluster Storage 3.2
for RHEL 7.

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.

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.

The following packages have been upgraded to a later upstream version:
samba (4.4.6). (BZ#1382287)

Security Fix(es) :

* It was found that Samba always requested forwardable tickets when
using Kerberos authentication. A service to which Samba authenticated
using Kerberos could subsequently use the ticket to impersonate Samba
to other services or domain users. (CVE-2016-2125)

* A flaw was found in the way Samba handled PAC (Privilege Attribute
Certificate) checksums. A remote, authenticated attacker could use
this flaw to crash the winbindd process. (CVE-2016-2126)

Enhancement(s) :

* gluster vfs plugin now supports more than one volfile servers. Samba
tries to connect to the next server on the list if one of the gluster
server is not reachable. (BZ#1330081)"
