+FreeBSD-EN-14:10.tzdata Errata Notice
+ The FreeBSD Project
+
+Topic: Time zone data file update
+
+Category: contrib
+Module: zoneinfo
+Announced: 2014-10-22
+Affects: All supported versions of FreeBSD prior to FreeBSD 10.1-BETA1
+Corrected: 2014-08-29 13:41:21 UTC (stable/10, 10.1-PRERELEASE)
+ 2014-10-21 23:52:25 UTC (releng/10.0, 10.0-RELEASE-p11)

+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:http://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 these software has to be updated separately. For software
+packages that is installed via package collection, they can be
+upgraded by doing a `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.
+
+2) To update your present 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.

+
+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:http://www.FreeBSD.org/handbook/makeworld.html>.
+
+Restart all the affected applications and daemons, or reboot the system.
+
+3) 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:

+Category: core

+
+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:http://security.freebsd.org/>.
+
+I. Background
+
+The crypt(3) function performs password hashing. Different algorithms
+of varying strength are available, with older, weaker algorithms being
+retained for compatibility.
+
+The crypt(3) function was originally based on the DES encryption
+algorithm and generated a 13-character hash from an eight-character
+password (longer passwords were truncated) and a two-character salt.
+
+II. Problem Description
+
+In recent FreeBSD releases, the default algorithm for crypt(3) was
+changed to SHA-512, which generates a much longer hash than the
+traditional DES-based algorithm.
+
+III. Impact
+
+Many applications assume that crypt(3) always returns a traditional DES
+hash, and blindly copy it into a short buffer without bounds checks. This
+may lead to a variety of undesirable results including, at worst, crashing
+the application.
+
+IV. Workaround
+
+No workaround is available.
+
+V. Solution
+
+Perform one of the following:
+
+1) Upgrade your system to a supported FreeBSD stable or release / security
+branch (releng) dated after the correction date.
+
+2) To update your present system via a source code patch:
+
+The following patches have been verified to apply to the applicable
+FreeBSD release branches.

+
+b) Apply the patch. Execute the following commands as root:

+# cd /usr/src

+
+c) Recompile the operating system using buildworld and installworld as

+

+
++# From Gunther Vermier (2015-05-13):

++
++# From Imed Chihi (2014-06-04):
++# We have finally "located" a precise official reference about the DST changes
++# in Egypt. The Ministers Cabinet decision is explained at
++# http://www.cabinet.gov.eg/Media/CabinetMeetingsDetails.aspx?id=347 ...
++# [T]his (Arabic) site is not accessible outside Egypt, but the page ...
++# translates into: "With regard to daylight saving time, it is scheduled to
++# take effect at exactly twelve o'clock this evening, Thursday, 15 MAY 2014,
++# to be suspended by twelve o'clock on the evening of Thursday, 26 JUN 2014,
++# and re-established again at the end of the month of Ramadan, at twelve
++# o'clock on the evening of Thursday, 31 JUL 2014." This statement has been
++# reproduced by other (more accessible) sites[, e.g.,]...
++# http://elgornal.net/news/news.aspx?id=4699258
++
++# From Paul Eggert (2014-06-04):
++# Sarah El Deeb and Lee Keath of AP report that the Egyptian government says
++# the change is because of blackouts in Cairo, even though Ahram Online (cited
++# above) says DST had no affect on electricity consumption. There is
++# no information about when DST will end this fall. See:
++# http://abcnews.go.com/International/wireStory/el-sissi-pushes-egyptians-line-23614833
++#
++# For now, guess that later spring and fall transitions will use
++# 2010's rules, and guess that Egypt will switch to standard time at
++# 24:00 the last Thursday before Ramadan, and back to DST at 00:00 the
++# first Friday after Ramadan. To implement this,
++# transition dates for 2015 through 2037 were determined by running
++# the following program under GNU Emacs 24.3, with the results integrated
++# by hand into the table below. Ramadan again intrudes on the guessed
++# DST starting in 2038, but that's beyond our somewhat-arbitrary cutoff.
