"Samba was updated to fix three security issues.

These security issues were fixed :

CVE-2016-2110: A man-in-the-middle could have downgraded NTLMSSP
authentication (bso#11688, bsc#973031).

CVE-2016-2111: Domain controller netlogon member computer could have
been spoofed (bso#11749, bsc#973032).

CVE-2015-5252: Insufficient symlink verification (allowed file access
outside the share) (bso#11395, bnc#958582).

The update package also includes non-security fixes. See advisory for
details.

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
