==============================
+ Release Notes for Samba 4.4.12
+ March 23, 2017
+ ==============================
+
+
+This is a security release in order to address the following defect:
+
+o CVE-2017-2619 (Symlink race allows access outside share definition)
+
+=======
+Details
+=======
+
+o CVE-2017-2619:
+ All versions of Samba prior to 4.6.1, 4.5.7, 4.4.11 are vulnerable to
+ a malicious client using a symlink race to allow access to areas of
+ the server file system not exported under the share definition.
+
+ Samba uses the realpath() system call to ensure when a client requests
+ access to a pathname that it is under the exported share path on the
+ server file system.
+
+ Clients that have write access to the exported part of the file system
+ via SMB1 unix extensions or NFS to create symlinks can race the server
+ by renaming a realpath() checked path and then creating a symlink. If
+ the client wins the race it can cause the server to access the new
+ symlink target after the exported share path check has been done. This
+ new symlink target can point to anywhere on the server file system.
+
+ This is a difficult race to win, but theoretically possible. Note that
+ the proof of concept code supplied wins the race reliably only when
+ the server is slowed down using the strace utility running on the
+ server. Exploitation of this bug has not been seen in the wild.
+
+
+Changes since 4.4.11:
+---------------------
+
+o Jeremy Allison <jra at samba.org>
+ * BUG 12496: CVE-2017-2619: Symlink race permits opening files outside share
+ directory.
