+Title: systemd-tmpfiles replaces opentmpfiles due to security issues
+Author: Georgy Yakovlev <gyakovlev@gentoo.org>
+Author: Sam James <sam@gentoo.org>
+Posted: 2021-07-07
+Revision: 1
+News-Item-Format: 2.0
+Display-If-Installed: virtual/tmpfiles
+
+On 2021-07-06, the sys-apps/opentmpfiles package was masked due to a
+root privilege escalation vulnerability (CVE-2017-18925 [0],
+bug #751415 [1], issue 4 [2] upstream).
+
+The use of opentmpfiles is discouraged by its maintainer due to the
+unpatched vulnerability and other long-standing bugs [3].
+
+Users will start seeing their package manager trying to replace
+sys-apps/opentmpfiles with sys-apps/systemd-tmpfiles because it is
+another provider of virtual/tmpfiles.
+
+Despite the name, 'systemd-tmpfiles' does not depend on systemd, does
+not use dbus, and is just a drop-in replacement for opentmpfiles. It is
+a small binary built from systemd source code, but works separately,
+similarly to eudev or elogind. It is known to work on both glibc and
+musl systems.
+
+Note that systemd-tmpfiles is specifically for non-systemd systems. It
+is intended to be used on an OpenRC system.
+
+If you wish to selectively test systemd-tmpfiles, follow those steps:
+
+ 1. # emerge --oneshot sys-apps/systemd-tmpfiles
+ 2. # reboot
+
+No other steps required.
+
+If, after reviewing the linked bug reference for opentmpfiles, you feel
+your system is not vulnerable/applicable to the attack described, you
+can unmask[4] opentmpfiles at your own risk:
+
+1. In /etc/portage/package.unmask, add:
+-sys-apps/opentmpfiles
+2. # emerge --oneshot sys-apps/opentmpfiles
