Synopsis
========

Multiple vulnerabilities have been discovered in systemd, the worst of
which could result in denial of service.

Background
==========

A system and service manager.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/glsamaker/models/glsa.py", line 326, in generate_mail_table
    return self._generate_mail_table()
  File "/usr/local/lib/python3.9/site-packages/glsamaker/models/glsa.py", line 297, in _generate_mail_table

Description
===========

Multiple vulnerabilities have been discovered in systemd. Please review
the CVE identifiers referenced below for details.

Impact
======

Please review the referenced CVE identifiers for details.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All systemd users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-apps/systemd-251.3"

All systemd-utils users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-apps/systemd-utils-251.3"

Gentoo has discontinued support for sys-apps/systemd-tmpfiles, sys-
boot/systemd-boot, and sys-fs/udev. See the 2022-04-19-systemd-utils
news item. Users should unmerge it in favor of sys-apps/systemd-utils on
non-systemd systems:

  # emerge --ask --depclean --verbose "sys-apps/systemd-tmpfiles" "sys-boot/systemd-boot" "sys-fs/udev"
  # emerge --ask --verbose --oneshot ">=sys-apps/systemd-utils-251.3"
