+                   Release Notes for Samba 4.6.11
+                          November 21, 2017
+                   =============================
+
+
+This is a security release in order to address the following defects:
+
+o  CVE-2017-14746 (Use-after-free vulnerability.)
+o  CVE-2017-15275 (Server heap memory information leak.)
+
+
+=======
+Details
+=======
+
+o  CVE-2017-14746:
+   All versions of Samba from 4.0.0 onwards are vulnerable to a use after
+   free vulnerability, where a malicious SMB1 request can be used to
+   control the contents of heap memory via a deallocated heap pointer. It
+   is possible this may be used to compromise the SMB server.
+
+o  CVE-2017-15275:
+   All versions of Samba from 3.6.0 onwards are vulnerable to a heap
+   memory information leak, where server allocated heap memory may be
+   returned to the client without being cleared.
+
+   There is no known vulnerability associated with this error, but
+   uncleared heap memory may contain previously used data that may help
+   an attacker compromise the server via other methods. Uncleared heap
+   memory may potentially contain password hashes or other high-value
+   data.
+
+For more details and workarounds, please see the security advisories:
