The PostgreSQL Global Development Group has released an update to all supported \ 
versions of our database system, including 13.3, 12.7, 11.12, 10.17, and 9.6.22. \ 
This release closes three security vulnerabilities and fixes over 45 bugs \ 
reported over the last three months.

For the full list of changes, please review the release notes.

Security Issues

CVE-2021-32027: Buffer overrun from integer overflow in array subscripting \ 
calculations

Versions Affected: 9.6 - 13. The security team typically does not test \ 
unsupported versions, but this problem is quite old.

While modifying certain SQL array values, missing bounds checks let \ 
authenticated database users write arbitrary bytes to a wide area of server \ 
memory.

The PostgreSQL project thanks Tom Lane for reporting this problem.

CVE-2021-32028: Memory disclosure in INSERT ... ON CONFLICT ... DO UPDATE

Versions Affected: 9.6 - 13. The security team typically does not test \ 
unsupported versions. The feature first appeared in 9.5.

Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted \ 
table, an attacker can read arbitrary bytes of server memory. In the default \ 
configuration, any authenticated database user can create prerequisite objects \ 
and complete this attack at will. A user lacking the CREATE and TEMPORARY \ 
privileges on all databases and the CREATE privilege on all schemas cannot use \ 
this attack at will.

The PostgreSQL project thanks Andres Freund for reporting this problem.

CVE-2021-32029: Memory disclosure in partitioned-table UPDATE ... RETURNING

Versions Affected: 11 - 13

Using an UPDATE ... RETURNING on a purpose-crafted partitioned table, an \ 
attacker can read arbitrary bytes of server memory. In the default \ 
configuration, any authenticated database user can create prerequisite objects \ 
and complete this attack at will. A user lacking the CREATE and TEMPORARY \ 
privileges on all databases and the CREATE privilege on all schemas typically \ 
cannot use this attack at will.

The PostgreSQL project thanks Tom Lane for reporting this problem.

Bug Fixes and Improvements

This update fixes over 45 bugs that were reported in the last several months. \ 
Some of these issues only affect version 13, but could also apply to other \ 
supported versions.

Some of these fixes include:

Fix potential incorrect computation of UPDATE ... RETURNING outputs for joined, \ 
cross-partition updates.
Fix ALTER TABLE ... ALTER CONSTRAINT when used on foreign-key constraints on \ 
partitioned tables. The command would fail to adjust the DEFERRABLE and/or \ 
INITIALLY DEFERRED properties of the constraints and triggers of leaf \ 
partitions, leading to unexpected behavior. After updating to this version, you \ 
can execute the ALTER TABLE ... ALTER CONSTRAINT command to fix any misbehaving \ 
partitioned tables.
Ensure that when a child table is attached with ALTER TABLE ... INHERIT that \ 
generated columns in the parent are generated in the same way in the child.
Forbid marking an identity column as NULL.
Allow ALTER ROLE ... SET/ALTER DATABASE ... SET to set the role, \ 
session_authorization, and temp_buffers parameters.
Ensure that REINDEX CONCURRENTLY preserves any statistics target set for the index.
Fix an issue where, in some cases, saving records within AFTER triggers could \ 
cause crashes.
Fix how to_char() handles Roman-numeral month format codes with negative intervals.
Fix use of uninitialized value while parsing an \{m,n\} quantifier in a BRE-mode \ 
regular expression.
Fix "could not find pathkey item to sort" planner errors that occur in \ 
some situations when the sort key involves an aggregate or window function.
Fix issue with BRIN index bitmap scans that could lead to "could not open \ 
file" errors.
Fix potentially wrong answers from GIN tsvector index searches when there are \ 
many matching records.
Fixes for COMMIT AND CHAIN functionality on both the server and psql.
Avoid incorrect timeline change while recovering uncommitted two-phase \ 
transactions from WAL, which could lead to consistency issues and the inability \ 
to restart the server.
Ensure thatwal_sync_method is set to fdatasync by default on newer FreeBSD releases.
Disable the vacuum_cleanup_index_scale_factor parameter and storage option.
Fix several memory leaks in the server, including one with SSL/TLS parameter \ 
initialization.
Restore the previous behavior of \connect service=XYZ to psql, i.e. disallow \ 
environmental variables (e.g. PGPORT) from overriding entries in the service \ 
file.
Fix how pg_dump handles generated columns in partitioned tables.
Add additional checks to pg_upgrade for user tables containing non-upgradable \ 
data types.
On Windows, initdb now prints instructions about how to start the server with \ 
pg_ctl using backslash separators.
Fix pg_waldump to count XACT records correctly when generating per-record statistics.

postgresql: updated to 13.2, 12.6, 11.11, 10.16, 9.6.21, and 9.5.25

The PostgreSQL Global Development Group has released an update to all supported \ 
versions of our database system, including 13.2, 12.6, 11.11, 10.16, 9.6.21, and \ 
9.5.25. This release closes two security vulnerabilities and fixes over 80 bugs \ 
reported over the last three months.

Additionally, this is the final release of PostgreSQL 9.5. If you are running \ 
PostgreSQL 9.5 in a production environment, we suggest that you make plans to \ 
upgrade.

For the full list of changes, please review the release notes.

Security Issues

CVE-2021-3393: Partition constraint violation errors leak values of denied columns

Versions Affected: 11 - 13.

A user having an UPDATE privilege on a partitioned table but lacking the SELECT \ 
privilege on some column may be able to acquire denied-column values from an \ 
error message. This is similar to CVE-2014-8161, but the conditions to exploit \ 
are more rare.

The PostgreSQL project thanks Heikki Linnakangas for reporting this problem.

CVE-2021-20229: Single-column SELECT privilege enables reading all columns

Versions Affected: 13.

A user having a SELECT privilege on an individual column can craft a special \ 
query that returns all columns of the table.

Additionally, a stored view that uses column-level privileges will have \ 
incomplete column-usage bitmaps. In installations that depend on column-level \ 
permissions for security, it is recommended to execute CREATE OR REPLACE on all \ 
user-defined views to force them to be re-parsed.

The PostgreSQL project thanks Sven Klemm for reporting this problem.

Bug Fixes and Improvements

This update fixes over 80 bugs that were reported in the last several months. \ 
Some of these issues only affect version 13, but could also apply to other \ 
supported versions.

Some of these fixes include:

Fix an issue with GiST indexes where concurrent insertions could lead to a \ 
corrupt index with entries placed in the wrong pages. You should REINDEX any \ 
affected GiST indexes.
Fix CREATE INDEX CONCURRENTLY to ensure rows from concurrent prepared \ 
transactions are included in the index. Installations that have enabled prepared \ 
transactions should REINDEX any concurrently-built indexes.
Fix for possible incorrect query results when a hash aggregation is spilled to disk.
Fix edge case in incremental sort that could lead to sorting results incorrectly \ 
or a "retrieved too many tuples in a bounded sort" error.
Avoid crash when a CALL or DO statement that performs a transaction rollback is \ 
executed via extended query protocol, such as from prepared statements.
Fix a failure when a PL/pgSQL procedure used CALL on another procedure that has \ 
OUT parameters that executed a COMMIT or ROLLBACK.
Remove errors from BEFORE UPDATE triggers on partitioned tables for restrictions \ 
that no longer apply.
Several fixes for queries with joins that could lead to error messages such as \ 
"no relation entry for relid N" or "failed to build any N-way \ 
joins".
Do not consider parallel-restricted or set-returning functions in an ORDER BY \ 
expressions when trying to parallelize sorts.
Fix ALTER DEFAULT PRIVILEGES to handle duplicate arguments safely.
Several fixes in behavior when wal_level is set to minimal, including when \ 
tables are rewritten within a transaction.
Several fixes for CREATE TABLE LIKE.
Ensure that allocated disk space for a dropped relation (e.g. a table) is \ 
released promptly when a transaction is committed.
Fix progress reporting for CLUSTER.
Fix handling of backslash-escaped multibyte characters in COPY FROM.
Fix recently-introduced race conditions in LISTEN/NOTIFY queue handling.
Allow the jsonb concatenation operator (||) to handle all combinations of JSON \ 
data types.
Fix WAL-reading logic so that standbys can handle timeline switches correctly. \ 
This issue could have shown itself with errors like "requested WAL segment \ 
has already been removed".
Several leak fixes for the walsender process around logical decoding and replication.
Ensure that a nonempty value of krb_server_keyfile always overrides any setting \ 
of KRB5_KTNAME in the server environment
Several fixes for GSS encryption support.
Ensure the \connect command allows the use of a password in the \ 
connection_string argument.
Fix assorted bugs with the \help command.
Several fixes for pg_dump.
Ensure that pg_rewind accounts for all WAL when rewinding a standby server.
Fix memory leak in contrib/auto_explain.
Ensure all postgres_fdw connections are closed if the a user mapping or foreign \ 
server object those connections depend on are dropped.
Fix JIT compilation to be compatible with LLVM 11 and LLVM 12.
This update also contains tzdata release 2021a for DST law changes in Russia \ 
(Volgograd zone) and South Sudan, plus historical corrections for Australia, \ 
Bahamas, Belize, Bermuda, Ghana, Israel, Kenya, Nigeria, Palestine, Seychelles, \ 
and Vanuatu.

Notably, the Australia/Currie zone has been corrected to the point where it is \ 
identical to Australia/Hobart.

For the full list of changes available, please review the release notes.

PostgreSQL 9.5 is EOL

This is the final release of PostgreSQL 9.5. If you are running PostgreSQL 9.5 \ 
in a production environment, we suggest that you make plans to upgrade to a \ 
newer, supported version of PostgreSQL. Please see our versioning policy for \ 
more information.

* CVE-2020-25695: Multiple features escape "security restricted \ 
operation" sandbox
* CVE-2020-25694: Reconnection can downgrade connection security settings
* CVE-2020-25696: psql's \gset allows overwriting specially treated variables

Bug Fixes and Improvements

This update also fixes over 65 bugs that were reported in the last several \ 
months. Some of these issues only affect version 13, but may also apply to other \ 
supported versions.

Some of these fixes include:

Fix a breakage in the replication protocol by ensuring that two "command \ 
completion" events are expected for START_REPLICATION.
Ensure fsync is called on the SLRU caches that PostgreSQL maintains. This \ 
prevents potential data loss due to an operating system crash.
Fix ALTER ROLE usage for users with the BYPASSRLS permission.
ALTER TABLE ONLY ... DROP EXPRESSION is disallowed on partitioned tables when \ 
there are child tables.
Ensure that ALTER TABLE ONLY ... ENABLE/DISABLE TRIGGER does not apply to child \ 
tables.
Fix for ALTER TABLE ... SET NOT NULL on partitioned tables to avoid a potential \ 
deadlock in parallel pg_restore.
Fix handling of expressions in CREATE TABLE LIKE with inheritance.
DROP INDEX CONCURRENTLY is disallowed on partitioned tables.
Allow LOCK TABLE to succeed on a self-referential view instead of throwing an error.
Several fixes around statistics collection and progress reporting for REINDEX \ 
CONCURRENTLY.
Ensure that GENERATED columns are updated when any columns they depend on are \ 
updated via a rule or an updatable view.
Support hash partitioning with text array columns as partition keys.
Allow the jsonpath .datetime() method to accept ISO 8601-format timestamps.
During a "smart" shutdown, ensure background processes are not \ 
terminated until all foreground client sessions are completed, fixing an issue \ 
that broke the processing of parallel queries.
Several fixes for the query planner and optimizer.
Ensure that data is de-toasted before being inserted into a BRIN index. This \ 
could manifest itself with errors like "missing chunk number 0 for toast \ 
value NNN". If you have seen a similar error in an existing BRIN index, you \ 
should be able to correct it by using REINDEX on the index.
Fix the output of EXPLAIN to have the correct XML tag nesting for incremental \ 
sort plans.
Several fixes for memory leaks, including ones involving RLS policies, using \ 
CALL with PL/pgSQL, SIGHUP processing a configuration parameter that cannot be \ 
applied without a restart, and an edge-case for index lookup for a partition.
libpq can now support arbitrary-length lines in the .pgpass file.
On Windows, psql now reads the output of a backtick command in text mode, not \ 
binary mode, so it can now properly handle newlines.
Fix how pg_dump, pg_restore, clusterdb, reindexdb, and vacuumdb use complex \ 
connection-string parameters.
When the \connect command of psql reuses connection parameters, ensure that all \ 
non-overridden parameters from a previous connection string are also re-used.
Ensure that pg_dump collects per-column information about extension \ 
configuration tables, avoiding crashes when specifying --inserts.
Ensure that parallel pg_restore processes foreign keys referencing partitioned \ 
tables in the correct order.
Several fixes for contrib/pgcrypto, including a memory leak fix.

Security Issues

CVE-2020-14349: Uncontrolled search path element in logical replication.
Versions Affected: 10 - 12.

The PostgreSQL search_path setting determines schemas searched for tables, \ 
functions, operators, etc. The CVE-2018-1058 fix caused most PostgreSQL-provided \ 
client applications to sanitize search_path, but logical replication continued \ 
to leave search_path unchanged. Users of a replication publisher or subscriber \ 
database can create objects in the public schema and harness them to execute \ 
arbitrary SQL functions under the identity running replication, often a \ 
superuser. Installations having adopted a documented secure schema usage pattern \ 
are not vulnerable.

The PostgreSQL project thanks Noah Misch for reporting this problem.

CVE-2020-14350: Uncontrolled search path element in CREATE EXTENSION.
Versions Affected: 9.5 - 12. The security team typically does not test \ 
unsupported versions, but this problem is quite old.

When a superuser runs certain CREATE EXTENSION statements, users may be able to \ 
execute arbitrary SQL functions under the identity of that superuser. The \ 
attacker must have permission to create objects in the new extension's schema or \ 
a schema of a prerequisite extension. Not all extensions are vulnerable.

In addition to correcting the extensions provided with PostgreSQL, the \ 
PostgreSQL Global Development Group is issuing guidance for third-party \ 
extension authors to secure their own work.

Bug Fixes and Improvements

This update also fixes over 50 bugs that were reported in the last several \ 
months. Some of these issues affect only version 12, but many affect all \ 
supported versions.

Some of these fixes include:

Fix edge cases in partition pruning involving multiple partition key columns \ 
with multiple or no constraining WHERE clauses.
Several fixes for query planning and execution involving partitions.
Fix for determining when to execute a column-specific UPDATE trigger on a \ 
logical replication subscriber.
pg_replication_slot_advance() now updates the oldest xmin and LSN values, as the \ 
failure to do this could prevent resources (e.g. WAL files) from being cleaned \ 
up.
Fix a performance regression in ts_headline().
Ensure that pg_read_file() and related functions read until EOF is reached, \ 
which fixes compatibility with pipes and other virtual files.
Forbid numeric NaN values in jsonpath computations, which do not exist in SQL \ 
nor JSON.
Several fixes for NaN inputs with aggregate functions. This fixes a change in \ 
PostgreSQL 12 where NaN values caused the following aggregates to emit values of \ 
0 instead of NaN: corr(), covar_pop(), regr_intercept(), regr_r2(), \ 
regr_slope(), regr_sxx(), regr_sxy(), regr_syy(), stddev_pop(), and var_pop().
time and timetz values fractionally greater than 24:00:00 are now rejected.
Several fixes for EXPLAIN, including a fix for reporting resource usage when a \ 
plan uses parallel workers with "Gather Merge" nodes.
Fix timing of constraint revalidation in ALTER TABLE that could lead to odd errors.
Fix for REINDEX CONCURRENTLY that could prevent old values from being included \ 
in future logical decoding output.
Fix for LATERAL references that could potentially cause crashes during query \ 
execution.
Use the collation specified for a query when estimating operator costs
Fix conflict-checking anomalies in SERIALIZABLE transaction isolation mode.
Ensure checkpointer process discards file sync requests when fsync is off
Fix issue where pg_control could be written out with an inconsistent checksum, \ 
which could lead to the inability to restart the database if it crashed before \ 
the next pg_control update.
Ensure that libpq continues to try to read from the database connection socket \ 
after a write failure, as this allows the connection to collect any final error \ 
messages from the server.
Report out-of-disk-space errors properly in pg_dump and pg_basebackup
Several fixes for pg_restore, including a fix for parallel restore on tables \ 
that have both table-level and column-level privileges.
Fix for pg_upgrade to ensure it runs with vacuum_defer_cleanup_age set to 0.
Fix how pg_rewind handles just-deleted files in the source data directory
Fix failure to initialize local state correctly in contrib/dblink, which could \ 
lead to dblink_close() issuing an unexpected COMMIT on the remote server.
Change contrib/amcheck to not report about deleted index pages that are empty, \ 
as this is normal during WAL replay.

PostgreSQL 12.3, 11.8, 10.13, 9.6.18, and 9.5.22 Released!

Posted on 2020-05-14 by PostgreSQL Global Development Group
The PostgreSQL Global Development Group has released an update to all supported \ 
versions of our database system, including 12.3, 11.8, 10.13, 9.6.18, and \ 
9.5.22. This release fixes one security issue found in the PostgreSQL server and \ 
over 75 bugs reported over the last three months.

Please plan to update at your earliest convenience.

Security Issues

CVE-2020-10733: Windows installer runs executables from uncontrolled directories.
Versions Affected: 9.5 - 12. The security team does not test unsupported \ 
versions, but this issue existed before PostgreSQL 9.5.

The Windows installer for PostgreSQL invokes system-provided executables that do \ 
not have fully-qualified paths. Executables in the directory where the installer \ 
loads or the current working directory take precedence over the intended \ 
executables. An attacker having permission to add files into one of those \ 
directories can use this to execute arbitrary code with the installer's \ 
administrative rights.

The PostgreSQL project thanks Hou JingYi (@hjy79425575) for reporting this problem.

Bug Fixes and Improvements

This update also fixes over 75 bugs that were reported in the last several \ 
months. Some of these issues affect only version 12, but may also affect all \ 
supported versions.

Some of these fixes include:

Several fixes for GENERATED columns, including an issue where it was possible to \ 
crash or corrupt data in a table when the output of the generated column was the \ 
exact copy of a physical column on the table, e.g. if the expression called a \ 
function which could return its own input.
Several fixes for ALTER TABLE, including ensuring the SET STORAGE directive is \ 
propagated to a table's indexes.
Fix a potential race condition when using DROP OWNED BY while another session is \ 
deleting the same objects.
Allow for a partition to be detached when it has inherited ROW triggers.
Several fixes for REINDEX CONCURRENTLY, particularly with issues when a REINDEX \ 
CONCURRENTLY operation fails.
Fix crash when COLLATE is applied to an uncollatable type in a partition bound \ 
expression.
Fix performance regression in floating point overflow/underflow detection.
Several fixes for full text search, particularly with phrase searching.
Fix query-lifespan memory leak for a set-returning function used in a query's \ 
FROM clause.
Several reporting fixes for the output of VACUUM VERBOSE.
Allow input of type circle to accept the format (x,y),r, which is specified in \ 
the documentation.
Allow for the get_bit() and set_bit() functions to not fail on bytea strings \ 
longer than 256MB.
Avoid premature recycling of WAL segments during crash recovery, which could \ 
lead to WAL segments being recycled before being archived.
Avoid attempting to fetch nonexistent WAL files from archive storage during \ 
recovery by skipping irrelevant timelines.
Several fixes for logical replication and replication slots.
Fix several race conditions in synchronous standby management, including one \ 
that occurred when changing the synchronous_standby_names setting.
Several fixes for GSSAPI support, include a fix for a memory leak that occurred \ 
when using GSSAPI encryption.
Ensure that members of the pg_read_all_stats role can read all statistics views.
Fix performance regression in information_schema.triggers view.
Fix memory leak in libpq when using sslmode=verify-full.
Fix crash in psql when attempting to re-establish a failed connection.
Allow tab-completion of the filename argument to \gx command in psql.
Add pg_dump support for ALTER ... DEPENDS ON EXTENSION.
Several other fixes for pg_dump, which include dumping comments on RLS policies \ 
and postponing restore of event triggers until the end.
Ensure pg_basebackup generates valid tar files.
pg_checksums skips tablespace subdirectories that belong to a different \ 
PostgreSQL major version
Several Windows compatibility fixes
This update also contains tzdata release 2020a for DST law changes in Morocco \ 
and the Canadian Yukon, plus historical corrections for Shanghai. The \ 
America/Godthab zone has been renamed to America/Nuuk to reflect current English \ 
usage ; however, the old name remains available as a compatibility link. This \ 
also updates initdb's list of known Windows time zone names to include recent \ 
additions.
