=====================================================================
1. Summary:
An update for samba is now available for Red Hat Gluster Storage 3.5 on 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.
2. Relevant releases/architectures:
Red Hat Gluster 3.5 Samba on RHEL-7 - 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 Samba packages have been upgraded to upstream version 4.10.4, which
provides a number of bug fixes and enhancements over the previous version.
(BZ#1776952)
Security Fix(es):
* samba: smb client vulnerable to filenames containing path separators
(CVE-2019-10218)
* samba: Crash after failed character conversion at log level 3 or above
(CVE-2019-14907)
Bug Fix(es):
* Earlier, the directory entries did not initialize completely and hence
Samba did not check correctly for DFS redirects. The Windows Explorer did
not display the DFS redirects properly and instead of showing the redirects
as directories, Samba displayed the redirects as files. With this fix, the
Samba's vfs_glusterfs module has been fixed so that DFS redirects now work
as expected. (BZ#1784827)
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.
For details on migrating Samba/CTDB configuration files, refer to:
https://access.redhat.com/solutions/4311261

1763137 - CVE-2019-10218 samba: smb client vulnerable to filenames containing path separators
