Advisory ID: RHSA-2019:4023-01
Product: Red Hat Gluster Storage
Advisory URL: https://access.redhat.com/errata/RHSA-2019:4023
Issue date: 2019-12-02
CVE Names: CVE-2019-10197
=====================================================================
1. Summary:
An update for samba is now available for Red Hat Gluster Storage 3.5 on 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 Gluster 3.5 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
allows PC-compatible machines to share files, printers, and various
information.
The following packages have been upgraded to a later upstream version:
samba (4.9.8). (BZ#1724260)
Security Fix(es):
* samba: Combination of parameters and permissions can allow the user to
escape from the share path definition (CVE-2019-10197)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
Bug Fix(es):
* The samba packages have been upgraded to upstream version 4.9.8 which
provides a number of bug fixes and enhancements over the previous version.
(BZ#1724260)
* Previously, CTDB was unable to start due to a missing filesystem
directory. In spite of manually creating the directory, CTDB could not
function properly due to an incorrect SELinux context. With this update,
the rpm package now properly creates the missing directory with the
required SELinux context and CTDB starts correctly. (BZ#1772836)
Users of Samba with Red Hat Gluster Storage are advised to upgrade to these
updated packages.
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/):
1724260 - [RHEL6] [Rebase] Samba rebuild required with new glusterfs
1746225 - CVE-2019-10197 samba: Combination of parameters and permissions can allow user to escape from the share path definition
