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.=C2=A0 =C2=A0Background

The IANA Time Zone Database (often called tz or zoneinfo) contains code and=
data that represent the history of local time for many representative
locations around the globe.=C2=A0 It is updated periodically to reflect cha= nges
made by political bodies to time zone boundaries, UTC offsets, and
daylight-saving rules.

FreeBSD releases install the IANA Time Zone Database in /usr/share/zoneinfo= .
The tzsetup(8) utility allows the user to specify the default local time zone.=C2=A0 Based on the selected time zone, tzsetup(8) copies one of the f= iles
from /usr/share/zoneinfo to /etc/localtime.=C2=A0 A time zone may also be s= elected
for an individual process by setting its TZ environment variable to a desir= ed
time zone name.

II.=C2=A0 Problem Description

Several changes to future and past timestamps have been recorded in the IAN= A
Time Zone Database after previous FreeBSD releases were released.=C2=A0 Thi= s
affects many users in different parts of the world.=C2=A0 Because of these<= br> changes, the data in the zoneinfo files need to be updated.=C2=A0 If the lo= cal
timezone on the running system is affected, tzsetup(8) needs to be run to update /etc/localtime.

III. Impact

An incorrect time will be displayed on a system configured to use one of th= e
affected time zones if the /usr/share/zoneinfo and /etc/localtime files are=
not updated, and all applications on the system that rely on the system tim= e,
such as cron(8) and syslog(8), will be affected.

IV.=C2=A0 Workaround

The system administrator can install an updated version of the IANA Time Zo= ne
Database from the misc/zoneinfo port and run tzsetup(8).

Applications that store and display times in Coordinated Universal Time (UT= C)
are not affected.

V.=C2=A0 =C2=A0Solution

Upgrade your system to a supported FreeBSD stable or release / security
branch (releng) dated after the correction date.

Please note that some third party software, for instance PHP, Ruby, Java, Perl and Python, may be using different zoneinfo data sources, in such case= s
this software must be updated separately.=C2=A0 Software packages that are<= br> installed via binary packages can be upgraded by executing 'pkg upgrade= '.

Following the instructions in this Errata Notice will only update the IANA<= br> Time Zone Database installed in /usr/share/zoneinfo.

Perform one of the following:

1) To update your system via a binary patch:

Systems running a RELEASE version of FreeBSD on the amd64, i386, or
(on FreeBSD 13 and later) arm64 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.
2) 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-23:05/tzdata-2023c.patch
# fetch https://security.FreeBSD= .org/patches/EN-23:05/tzdata-2023c.patch.asc
# gpg --verify tzdata-2023c.patch.asc

b) Apply the patch.=C2=A0 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.

For FreeBSD 13 and later:

Run the following command to see which files were modified by a
particular commit:

# git show --stat <commit hash>

Or visit the following URL, replacing NNNNNN with the hash:

<URL:https://cgit.freebsd.org/src/commit/?id=3DNN= NNNN>

To determine the commit count in a working tree (for comparison against
nNNNNNN in the table above), run:

# git rev-list --count --first-parent HEAD

For FreeBSD 12 and earlier:

Run the following command to see which files were modified by a particular<= br> revision, replacing NNNNNN with the revision number:

# svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base

Or visit the following URL, replacing NNNNNN with the revision number:

<URL:https://svnweb.freebsd.= org/base?view=3Drevision&revision=3DNNNNNN>
