Description :

An update for samba is now available for Red Hat Gluster Storage 3.2
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) :

* 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)
