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. HPE NonStop Server is affected.

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:   HPE has issued a fix for CVE-2017-12150 and CVE-2017-12163 for HPE NonStop Server.

HPE NonStop Server is not affected by CVE-2017-12151.
