Synopsis

The remote Red Hat host is missing one or more security updates.

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)

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.
