supported versions of our database system, including 11.3, 10.8, 9.6.13,
9.5.17, and 9.4.22. This release fixes two security issues in the
PostgreSQL server, a security issue found in two of the PostgreSQL
Windows installers, and over 60 bugs reported over the last three months.
Security: CVE-2019-10129: Memory disclosure in partition routing
Prior to this release, a user running PostgreSQL 11 can read arbitrary
bytes of server memory by executing a purpose-crafted INSERT statement
to a partitioned table.
Security: CVE-2019-10130: Selectivity estimators bypass row security policies
PostgreSQL maintains statistics for tables by sampling data available in
columns; this data is consulted during the query planning process. Prior
to this release, a user able to execute SQL queries with permissions to
read a given column could craft a leaky operator that could read
whatever data had been sampled from that column. If this happened to
include values from rows that the user is forbidden to see by a row
security policy, the user could effectively bypass the policy. This is
fixed by only allowing a non-leakproof operator to use this data if
there are no relevant row security policies for the table.
This issue is present in PostgreSQL 9.5, 9.6, 10, and 11. The PostgreSQL
project thanks Dean Rasheed for reporting this problem.
Also fix a FreeBSD port problem with LLVM [1] and add promote command
to `service postgresql` [2]

2018-02-08 Security Update Release
==================================
The PostgreSQL Global Development Group has released an update to all supported
versions of our database system, including 10.2, 9.6.7, 9.5.11, 9.4.16, 9.3.21.
This release fixes two security issues. This release also fixes issues with
VACUUM, GIN indexes, and hash indexes that could lead to data corruption, as
well as fixes for using parallel queries and logical replication.
All users using the affected versions of PostgreSQL should update as soon as
possible. Please see the notes on "Updating" below for any post-update steps
that may be required.
Please note that PostgreSQL changed its versioning scheme with the release of
version 10.0, so updating to version 10.2 from 10.0 or 10.1 is considered a
minor update.
Security Issues
---------------
Two security vulnerabilities have been fixed by this release:
* CVE-2018-1052: Fix the processing of partition keys containing multiple
expressions
* CVE-2018-1053: Ensure that all temporary files made with "pg_upgrade" are
non-world-readable
Local fixes to the FreeBSD ports
--------------------------------
Inform users about data checksums [1].
Make sure /usr/bin/su is used regardless of PATH settings [2].
Enable DTRACE by default [3].

The PostgreSQL Global Development Group has released an update to all supported
versions of our database system, including 9.6.3, 9.5.7, 9.4.12, 9.3.17, and
9.2.21. This release fixes three security issues. It also patches a number of
other bugs reported over the last three months. Users who use the PGREQUIRESSL
environment variable to control connections, and users who rely on security
isolation between database users when using foreign servers, should update as
soon as possible. Other users should plan to update at the next convenient
downtime.

Also modify rcorder and let sshd start before PostgreSQL, so any problems
during startup can be reviewed promplty from an ssh login.

Security: CVE-2016-5423, CVE-2016-5424
Security Fixes for Regular Expressions, PL/Java
This release closes security hole CVE-2016-0773, an issue with regular
expression (regex) parsing. Prior code allowed users to pass in expressions
which included out-of-range Unicode characters, triggering a backend crash.
This issue is critical for PostgreSQL systems with untrusted users or which
generate regexes based on user input.
The update also fixes CVE-2016-0766, a privilege escalation issue for users of
PL/Java. Certain custom configuration settings (GUCS) for PL/Java will now be
modifiable only by the database superuser

pg_upgrade. Other where added in 9.5, but the port failed to install them.
Make sure they are properly installed by the correct port (-client or -server) [1]
Remove unused and hence confusing OSSP_UUID parameters from Makefile [2]
Add options to allow user to be set for the backup script in periodic.
Add this option only to 9.5 for now. It will be updated to other servers at
next regular patch release. [3]
The path to perl in hard coded into pgxs/src/Makefile.global which is
then installed. Hence, we must depend on perl when that file is installed.
