RHEL 8 : systemd (RHSA-2024:1105)

high Nessus Plugin ID 191581

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for systemd.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:1105 advisory.

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: buffer overrun in format_timespan() function (CVE-2022-3821)

* systemd: local information leak due to systemd-coredump not respecting fs.suid_dumpable kernel setting (CVE-2022-4415)

* 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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL systemd package based on the guidance in RHSA-2024:1105.
