Synopsis :

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

Description :

Updated samba packages that fix one security issue are now available
for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

Samba is an open source implementation of the Server Message Block
(SMB) or Common Internet File System (CIFS) protocol, which allows
PC-compatible machines to share files, printers, and other
information.

A flaw was found in the way Samba handled ACLs on symbolic links. An
authenticated user could use this flaw to gain access to an arbitrary
file or directory by overwriting its ACL. (CVE-2015-7560)

Red Hat would like to thank the Samba project for reporting this
issue. Upstream acknowledges Jeremy Allison (Google) and the Samba
team as the original reporters.

All samba users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. After
installing this update, the smb service will be restarted
automatically.
