Oracle Linux 6 : samba4 (ELSA-2016-1487)

Medium Nessus Plugin ID 92577


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


From Red Hat Security Advisory 2016:1487 :

An update for samba4 is now available for Red Hat Enterprise Linux 6.

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) or Common Internet File System (CIFS) protocol, which allows PC-compatible machines to share files, printers, and other information.

Security Fix(es) :

* A flaw was found in the way Samba initiated signed DCE/RPC connections. A man-in-the-middle attacker could use this flaw to downgrade the connection to not use signing and therefore impersonate the server. (CVE-2016-2119)

Red Hat would like to thank the Samba project for reporting this issue. Upstream acknowledges Stefan Metzmacher as the original reporter.


Update the affected samba4 packages.
