Synopsis
The remote openSUSE host is missing a security update.
Description
This update for salt fixes the following issues :
- 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)
- Xen disk fixes. No longer generates volumes for Xen disks, but the corresponding file or block disk. (bsc#1175987)
- Invalidate file list cache when cache file modified time is in the future. (bsc#1176397)
- Prevent import errors when running test_btrfs unit tests
This update was imported from the SUSE:SLE-15-SP1:Update update project.
