FreeBSD-EN-20:08.tzdata Errata Notice
|
|
The FreeBSD Project
|
|
|
|
Topic: Timezone database information update
|
|
|
|
Category: contrib
|
|
Module: zoneinfo
|
|
Announced: 2020-05-12
|
|
Affects: All supported versions of FreeBSD.
|
|
Corrected: 2020-04-27 03:56:47 UTC (stable/12, 12.1-STABLE)
|
|
2020-05-12 16:44:13 UTC (releng/12.1, 12.1-RELEASE-p5)
|
|
2020-04-27 03:57:17 UTC (stable/11, 11.4-PRERELEASE)
|
|
2020-05-12 16:44:13 UTC (releng/11.3, 11.3-RELEASE-p9)
|
|
|
|
Note: The upcoming release of FreeBSD 11.4 was branched after the original
|
|
commit to the stable branch and already includes the updated timezone
|
|
information.
|
|
|
|
For general information regarding FreeBSD Errata Notices and Security
|
|
Advisories, including descriptions of the fields above, security
|
|
branches, and the following sections, please visit
|
|
<URL:https://security.FreeBSD.org/>.
|
|
|
|
I. Background
|
|
|
|
The tzsetup(8) program allows the user to specify the default local timezone.
|
|
Based on the selected timezone, tzsetup(8) copies one of the files from
|
|
/usr/share/zoneinfo to /etc/localtime. This file actually controls the
|
|
conversion.
|
|
|
|
II. Problem Description
|
|
|
|
Several changes in Daylight Savings Time happened after previous FreeBSD
|
|
releases were released that would affect many people who live in different
|
|
countries. Because of these changes, the data in the zoneinfo files need to
|
|
be updated, and if the local timezone on the running system is affected,
|
|
tzsetup(8) needs to be run so the /etc/localtime is updated.
|
|
|
|
III. Impact
|
|
|
|
An incorrect time will be displayed on a system configured to use one of the
|
|
affected timezones if the /usr/share/zoneinfo and /etc/localtime files are
|
|
not updated, and all applications on the system that rely on the system time,
|
|
such as cron(8) and syslog(8), will be affected.
|
|
|
|
IV. Workaround
|
|
|
|
The system administrator can install an updated timezone database from the
|
|
misc/zoneinfo port and run tzsetup(8) to get the timezone database corrected.
|
|
|
|
Applications that store and display times in Coordinated Universal Time (UTC)
|
|
are not affected.
|
|
|
|
V. Solution
|
|
|
|
Please note that some third party software, for instance PHP, Ruby, Java and
|
|
Perl, may be using different zoneinfo data source, in such cases this
|
|
software must be updated separately. For software packages that is installed
|
|
via binary packages, they can be upgraded by executing `pkg upgrade'.
|
|
|
|
Following the instructions in this Errata Notice will update all of the
|
|
zoneinfo files to be the same as what was released with FreeBSD release.
|
|
|
|
Perform one of the following:
|
|
|
|
1) Upgrade your system to a supported FreeBSD stable or release / security
|
|
branch (releng) dated after the correction date. Restart all the affected
|
|
applications and daemons, or reboot the system.
|
|
|
|
2) To update your system via a binary patch:
|
|
|
|
Systems running a RELEASE version of FreeBSD on the i386 or amd64
|
|
platforms can be updated via the freebsd-update(8) utility:
|
|
|
|
# freebsd-update fetch
|
|
# freebsd-update install
|
|
|
|
Restart all the affected applications and daemons, or reboot the system.
|
|
|
|
3) To update your system via a source code patch:
|
|
|
|
The following patches have been verified to apply to the applicable
|
|
FreeBSD release branches.
|
|
|
|
a) Download the relevant patch from the location below, and verify the
|
|
detached PGP signature using your PGP utility.
|
|
|
|
# fetch https://security.FreeBSD.org/patches/EN-20:08/tzdata-2020a.patch
|
|
# fetch https://security.FreeBSD.org/patches/EN-20:08/tzdata-2020a.patch.asc
|
|
# gpg --verify tzdata-2020a.patch.asc
|
|
|
|
b) Apply the patch. Execute the following commands as root:
|
|
|
|
# cd /usr/src
|
|
# patch < /path/to/patch
|
|
|
|
c) Recompile the operating system using buildworld and installworld as
|
|
described in <URL:https://www.FreeBSD.org/handbook/makeworld.html>.
|
|
|
|
Restart all the affected applications and daemons, or reboot the system.
|
|
|
|
