high Nessus Plugin ID 92567

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

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.

Solution

Update the affected samba4 packages.
