Medium Nessus Plugin ID 89951


The remote Oracle Linux host is missing one or more security updates.


From Red Hat Security Advisory 2016:0448 :

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.
