openSUSE has rolled out a crucial security update for systemd, tackling significant vulnerabilities and implementing essential corrections.
An update that solves two vulnerabilities and has 7 fixes is now available.

Description

This update for systemd fixes the following issues:

Security issues fixed:

- core: skip unit deserialization and move to the next one when

unit_deserialize() fails

- core: properly handle deserialization of unknown unit types (#6476)

- core: don't create Requires for workdir if "missing ok" (bsc#1113083)

- logind: rework...
