A UNIX Symbolic Link (Symlink) Following vulnerability in the packaging of salt of SUSE Linux Enterprise Server 12, SUSE Linux Enterprise Server 15; openSUSE Factory allows local attackers to escalate privileges from user salt to root. This issue affects: SUSE Linux Enterprise Server 12 salt-master version 2019.2.0-46.83.1 and prior versions. SUSE Linux Enterprise Server 15 salt-master version 2019.2.0-6.21.1 and prior versions. openSUSE Factory salt-master version 2019.2.2-3.1 and prior versions.

This update fixes the following issues :

salt :

Fix for TypeError in Tornado importer (bsc#1174165)

Update to salt version 3000 See release notes:
https://docs.saltstack.com/en/latest/topics/releases/3000.html

Zypperpkg: filter patterns that start with dot (bsc#1171906)

Batch mode now also correctly provides return value (bsc#1168340)

Add docker.logout to docker execution module (bsc#1165572)

Testsuite fix

Add option to enable/disable force refresh for zypper

Python3.8 compatibility changes

Revert broken changes to slspath made on Salt 3000 (saltstack/salt#56341) (bsc#1170104)

Returns a the list of IPs filtered by the optional network list

Fix CVE-2020-11651 and CVE-2020-11652 (bsc#1170595)

Do not require vendored backports-abc (bsc#1170288)

Fix partition.mkpart to work without fstype (bsc#1169800)

Enable building and installation for Fedora

Disable python2 build on Tumbleweed We are removing the python2 interpreter from openSUSE (SLE16). As such disable salt building for python2 there.

More robust remote port detection

Sanitize grains loaded from roster_grains.json cache during 'state.pkg'

Do not make file.recurse state to fail when msgpack 0.5.4 (bsc#1167437)

Build: Buildequire pkgconfig(systemd) instead of systemd pkgconfig(systemd) is provided by systemd, so this is de-facto no change. But inside the Open Build Service (OBS), the same symbol is also provided by systemd-mini, which exists to shorten build-chains by only enabling what other packages need to successfully build

Add new custom SUSE capability for saltutil state module

Fixes status attribute issue in aptpkg test

Make setup.py script not to require setuptools greater than 9.1

Loop: fix variable names for until_no_eval
