New! Plugin Severity Now Using CVSS v3

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update fixes the following issues :

salt :

Avoid regression on 'salt-master': set passphrase for salt-ssh keys to empty string (bsc#1178485)

Properly validate eauth credentials and tokens on SSH calls made by Salt API (bsc#1178319, bsc#1178362, bsc#1178361, CVE-2020-25592, CVE-2020-17490, CVE-2020-16846)

Fix disk.blkid to avoid unexpected keyword argument '__pub_user' (bsc#1177867)

Ensure virt.update stop_on_reboot is updated with its default value

Do not break package building for systemd OSes

Drop wrong mock from chroot unit test

Support systemd versions with dot (bsc#1176294)

Fix for grains.test_core unit test

Fix file/directory user and group ownership containing UTF-8 characters (bsc#1176024)

Several changes to virtualization :

- Fix virt update when cpu and memory are changed

- Memory Tuning GSoC

- Properly fix memory setting regression in virt.update

- Expose libvirt on_reboot in virt states

Support transactional systems (MicroOS)

Zypperpkg module ignores retcode 104 for search() (bsc#1159670)

Invalidate file list cache when cache file modified time is in the future (bsc#1176397)

Prevent import errors when running test_btrfs unit tests

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.
