Does mitigation of the so-called BADLOCK CVE (CVE-2016-2118) for Samba 3.x imply an upgrade to a non-vulnerable version of the tdb library? If so, can someone point me to any documentation on the tdb vulnerability? Thanks, Sam

Do you know why Red Hat updated libtdb as part of their remediation for Badlock on Samba4? https://rhn.redhat.com/errata/RHSA-2016-0612.html On Thu, Jun 2, 2016 at 2:37 PM, Jeremy Allison <jra at samba.org> wrote: > On Thu, Jun 02, 2016 at 11:29:25AM -0500, Sam Gardner wrote: > > Does mitigation of the so-called BADLOCK CVE (CVE-2016-2118) for Samba > 3.x > > imply an

Hi, Microsoft some time ago introduced Hardened UNC Paths, and in April published the Badlock security fixes, which seem to be related to that. Samba at the same time published versions 4.4.1 (and 4.4.2). Even after reading the release notes of Samba 4.4.1 several times, I still do not know whether I must manually adjust smb.conf to be protected from these vulnerabilities. What I do know is

It's dead code because this is now handled in the core.

Hi everyone, I'm having the following situation: I need to migrate all SMB file services to a new appliance that only supports the SMB2+ protocol. Unfortunately, there are still some very old Linux clients ("modinfo cifs" says version 1.60) that do only speak SMB1 and need to access these shares after the migration. Is it possible to have a Linux with a modern Samba

We can't do that until we provide a reasonable way for SMB1 clients to connect, probably via a SMB1 -> SMB2 proxy based on the NTVFS file server (where we had such a prototype until very recently). It won't be perfect SMB1, but needs to be enough for basic operation. I'm quite convinced Samba and SMB1 are critical infrastructure in many places and while we may dislike SMB1 for

There were no tdb vulnerabilities in the badlock code release.

Hi, Samba has released patch for CVE-2016-2118 from 3.6.x release onwards. We use samba 3.0.35 in our product. Is there any patch available for 3.0.35? -- Regards Madhu

Hi, Due to "Red Hat Vulnerability Response: BADLOCK", an automatic samba package RHEL5 update was apply on our system. This broke "The trust relationship between this workstation and the primary domain failed" (error message logon client) in my environnement production. So, I use now 3.6.23-12.el5_11, I see they are new directive for smb.conf and some others more restrict

Hello, I run a CentOS 6 machine with samba, serving approx. 150 Windows users with samba running as an NT-like PDC. After today's samba update (samba-3.6.23-30.el6_7.x86_64 etc.), nobody can log in. They all get the "Trust relationship failed" error message. If I downgrade: yum downgrade samba-common samba-winbind samba-winbind-clients samba-client samba samba-doc

Just to follow up, the fix for us was to add "client ipc signing = auto" to our smb.conf configuration file.

Another follow up. I have a Centos 6 server running as a Samba NT4/PDC Domain controller and have seen the regression with 3.6.23-30 release. Client is a Windows 2008R2 server. Workaround with smb.conf parameters given here seems to work but it works only for accounts already existing in the domain. New accounts get a "There are currently no logon servers available to service the
