"This update for yast2-smt to 3.0.14 and smt to 3.0.37 fixes the
following issues :

These security issues were fixed in SMT :

CVE-2018-12471: Xml External Entity processing in the
RegistrationSharing modules allowed to read arbitrary file read
(bsc#1103809).

CVE-2018-12470: SQL injection in RegistrationSharing module allows
remote attackers to run arbitrary SQL statements (bsc#1103810).

CVE-2018-12472: Authentication bypass in sibling check facilitated
further attacks on SMT (bsc#1104076).

SUSE would like to thank Jake Miller for reporting these issues to us.

These non-security issues were fixed in SMT: Fix cron jobs
randomization (bsc#1097560)

Fix duplicate migration paths (bsc#1097824)

This non-security issue was fixed in yast2-smt: Remove cron job
rescheduling (bsc#1097560)

Added missing translation marks (bsc#1037811)

Explicitly mention 'Organization Credentials' (fate#321759)

Rearrange the SMT set-up dialog (bsc#977043)

Make the Filter button default (bsc#1006984)

Prevent exiting the repo selection dialog via hitting Enter in the
repository filter (bsc#1006984)

report when error occurs during repo mirroring (bsc#1006989)

Use TextEntry-based filter for repos (fate#319777)

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."
