Comment 1 David Walser 2020-11-02 18:23:43 CET
Ubuntu has issued an advisory for this today (November 2):
https://ubuntu.com/security/notices/USN-4611-1
Comment 2 Buchan Milne 2020-11-04 22:16:55 CET
Cauldron has samba-4.12.9-1.mga8

I haven't got a patch for mga7 (4.10.x) yet, will try and finish that tomorrow (or consider bumping mga7 to 4.12.9).

Status: NEW => ASSIGNED

Comment 3 David Walser 2020-11-04 22:22:02 CET
So far the only distro I see with 4.10.x updates is SUSE:

Comment 4 David Walser 2020-11-04 22:31:16 CET
SUSE just pulled an updated git snapshot from the 4.10.x branch.
Comment 5 Buchan Milne 2020-11-04 22:34:32 CET
I have patches for CVE-2020-14318 and CVE-2020-14323 that apply, but not yet for CVE-2020-14383.
Comment 6 David Walser 2020-11-04 22:38:12 CET
Strange, I don't see any commits upstream since 4.10.18 six weeks ago:
https://git.samba.org/samba.git/?p=samba.git;a=shortlog;h=refs/heads/v4-10-stable
Comment 7 Buchan Milne 2020-11-04 23:02:11 CET
r1642722 ( samba-4.10.18-1.1.mga7), just submitted to updates_testing, has patches for all 3 CVEs.

Advisory:
========================

Updated samba packages fix security vulnerabilities:

Steven French discovered that Samba incorrectly handled ChangeNotify
permissions. A remote attacker could possibly use this issue to obtain file
name information (CVE-2020-14318).

Bas Alberts discovered that Samba incorrectly handled certain winbind
requests. A remote attacker could possibly use this issue to cause winbind to
crash, resulting in a denial of service (CVE-2020-14323).

Francis Brosnan Blázquez discovered that Samba incorrectly handled certain
invalid DNS records. A remote attacker could possibly use this issue to cause
the DNS server to crash, resulting in a denial of service (CVE-2020-14383).

Comment 9 Herman Viaene 2020-11-09 10:55:39 CET
MGA7-64 MATE on Peaq C1011
No installation issues.
Ref bug 27299
Used MCC to define a minimum samba server, used webmin to define samba-user.
Using smbclient I could connect to my samba-server on my desktop PC, and similarly I could connect from my desktop PC to the samba server on this notebookj.
