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
-------------------------------------------------------------------
sys-apps/systemd < 251.3 >= 251.3
sys-apps/systemd-tmpfiles < 250
sys-apps/systemd-utils < 251.3 >= 251.3
sys-fs/udev < 250=20=20=20=20=20=20=20=20=20=20=20=20==20=20=20=20=20=20

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"
