==============================
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:
