(Red Hat Issues Fix) Samba Multiple Flaws Let Remote Users Hijack Connections and Remote Authenticated Users Obtain Potentially Sensitive Information
SecurityTracker Alert ID:  1039416
SecurityTracker URL:  http://securitytracker.com/id/1039416
CVE Reference:   CVE-2017-12150, CVE-2017-12151, CVE-2017-12163   (Links to External Site)
Date:  Sep 21 2017
Impact:   Disclosure of system information, Disclosure of user information, Modification of system information, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to versions 4.4.16, 4.5.14, and 4.6.8
Description:   Several vulnerabilities were reported in Samba. A remote user can access data on the target system. A remote user can modify data on the target system. A remote authenticated user can obtain potentially sensitive information on the target system.

The system fails to require SMB signing in certain cases. A remote user can conduct a man-in-the-middle attack to hijack client connections and obtain potentially sensitive information [CVE-2017-12150]. Versions 3.0.25 to 4.6.7 are affected.

The client software does not properly sign and encrypt DFS redirects when the max protocol for the original connection is set as 'SMB3' [CVE-2017-12151]. Versions 4.1.0 to 4.6.7 are affected.

A remote authenticated user can send specially crafted SMB1 data to cause portions of server memory contents to be written to a file on the target Samba share or to a shared printer [CVE-2017-12163].

Yihan Lian and Zhibin Hu, security researchers with Qihoo 360 GearTeam, and Stefan Metzmacher of SerNet (https://samba.plus) reported these vulnerabilities.

Impact:   A remote user can access and modify data communicated between the client and server.

A remote authenticated user can obtain potentially sensitive information from server memory on the target system.

Solution:   Red Hat has issued a fix.

3. Description:

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):

* It was found that samba did not enforce "SMB signing" when certain
configuration options were enabled. A remote attacker could launch a
man-in-the-middle attack and retrieve information in plain-text.
(CVE-2017-12150)

* A flaw was found in the way samba client used encryption with the max
protocol set as SMB3. The connection could lose the requirement for signing
and encrypting to any DFS redirects, allowing an attacker to read or alter
the contents of the connection via a man-in-the-middle attack.
(CVE-2017-12151)

* An information leak flaw was found in the way SMB1 protocol was
implemented by Samba. A malicious client could use this flaw to dump server
memory contents to a file on the samba share or to a shared printer, though
the exact area of server memory cannot be controlled by the attacker.
(CVE-2017-12163)

Red Hat would like to thank the Samba project for reporting CVE-2017-12150
and CVE-2017-12151 and Yihan Lian and Zhibin Hu (Qihoo 360 GearTeam),
Stefan Metzmacher (SerNet), and Jeremy Allison (Google) for reporting
CVE-2017-12163. Upstream acknowledges Stefan Metzmacher (SerNet) as the
original reporter of CVE-2017-12150 and CVE-2017-12151.
