CVE-2021-3677: Memory disclosure in certain queries

Versions Affected: 11 - 13.

A purpose-crafted query can read arbitrary bytes of server memory. In the \ 
default configuration, any authenticated database user can complete this attack \ 
at will. The attack does not require the ability to create objects. If server \ 
settings include max_worker_processes=0, the known versions of this attack are \ 
infeasible. However, undiscovered variants of the attack may be independent of \ 
that setting.

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 13, but many affect all \ 
supported versions.

Some of these fixes include:

Completely disable TLS/SSL renegotiation. This was previously disabled, but the \ 
server would still execute a client-initiated renegotiation request.
Restore the Portal-level snapshot after COMMIT or ROLLBACK within a procedure. \ 
This change fixes cases where an attempt to fetch a toasted value immediately \ 
after COMMIT/ROLLBACK would fail with errors like "no known snapshots" \ 
or "missing chunk number 0 for toast value".
Avoid misbehavior when persisting the output of a cursor that's reading a \ 
volatile query.
Reject cases where a query in WITH rewrites to just NOTIFY, which would cause a \ 
crash.
Several corner-case fixes for numeric types.
ALTER EXTENSION now locks the extension when adding or removing a member object.
The "enabled" status is now copied when a partitioned table's triggers \ 
are cloned to a new partition.
Avoid alias conflicts in queries generated for REFRESH MATERIALIZED VIEW \ 
CONCURRENTLY. This command failed on materialized views containing columns with \ 
certain names, notably mv and newdata.
Disallow whole-row variables in GENERATED expressions.
Several fixes for DROP OWNED BY behavior in relation to row-level security (RLS) \ 
policies.
Re-allow old-style Windows locale names in CREATE COLLATION commands.
walsenders now show their latest replication command in pg_stat_activity, \ 
instead of just showing the latest SQL command.
pg_settings.pending_restart now shows as true when a pertinent entry in \ 
postgresql.conf is removed.
On 64-bit Windows, allow the effective value of work_mem * hash_mem_multiplier \ 
to exceed 2GB.
Update minimum recovery point when WAL replay of a transaction abort record \ 
causes file truncation.
Advance oldest-required-WAL-segment horizon properly after a replication slot is \ 
invalidated. This fixes an issue where the server's WAL storage could run out of \ 
space.
Improve progress reporting for the sort phase of a parallel B-tree index build.
Fix assorted crash cases in logical replication of partitioned-table updates and \ 
when firing AFTER triggers of partitioned tables.
Prevent infinite loops in SP-GiST index insertion.
Ensure that SP-GiST index insertion can be terminated by a query cancel request.
In psql and other client programs, avoid overrunning the ends of strings when \ 
dealing with invalidly-encoded data.
Fix pg_dump to correctly handle triggers on partitioned tables whose enabled \ 
status is different from their parent triggers' status.
Avoid "invalid creation date in header" warnings when running \ 
pg_restore on a file created in a different time zone.
pg_upgrade now carries forward the old installation's oldestXID value and no \ 
longer forces an anti-wraparound VACUUM."
Extend pg_upgrade to detect and warn about extensions that should be upgraded.
Fix contrib/postgres_fdw to better work with generated columns, so long as a \ 
generated column in a foreign table represents a generated column in the remote \ 
table.

 PostgreSQL Project  Security
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.
