described in this advisory, refer to:
https://access.redhat.com/articles/11258
Summary
The systemd packages contain systemd, a system and service manager for
Linux, compatible with the SysV and LSB init scripts. It provides
aggressive parallelism capabilities, uses socket and D-Bus activation for
starting services, offers on-demand starting of daemons, and keeps track of
processes using Linux cgroups. In addition, it supports snapshotting and
restoring of the system state, maintains mount and automount points, and
implements an elaborate transactional dependency-based service control
logic. It can also work as a drop-in replacement for sysvinit.
Security Fix(es):
* systemd: privilege escalation via the less pager (CVE-2023-26604)
For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
Bug Fix(es):
* systemd-pstore crashes when attempting to move standalone files out of
/sys/fs/pstore (BZ#2190153)
