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):

* A race condition was found in samba server. A malicious samba client
could use this flaw to access files and directories in areas of the server
file system not exported under the share definitions. (CVE-2017-2619)

* 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)

* 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-2017-2619
and CVE-2017-12150 and Yihan Lian and Zhibin Hu (Qihoo 360 GearTeam),
Stefan Metzmacher (SerNet), and Jeremy Allison (Google) for reporting
CVE-2017-12163. Upstream acknowledges Jann Horn (Google) as the original
reporter of CVE-2017-2619  and Stefan Metzmacher (SerNet) as the original
reporter of CVE-2017-12150.
