Two significant vulnerabilities in systemd rectified in openSUSE 15.1 through essential updates and enhancements.
An update that solves two vulnerabilities and has 12 fixes is now available.

- libblkid: open device in nonblock mode. (bsc#1084671)

- udev/cdrom_id: Do not open CD-rom in exclusive mode. (bsc#1154256)

- bus_open leak sd_event_source when udevadm trigger。 (bsc#1161436

CVE-2019-20386)

- fileio: introduce read_full_virtual_file() for reading virtual files in

sysfs, procfs (bsc#1133495 bsc#1159814)

- fileio: initialize errno to zero before we do fread()

- fileio: try to read one byte too much in read_full_stream()

- logind: consider "greeter"...
