Fixes the following security issue:
CVE-2025-8713: PostgreSQL optimizer statistics can expose sampled data
within a view, partition, or child table
PostgreSQL optimizer statistics allow a user to read sampled data within
a view that the user cannot access. Separately, statistics allow a user
to read sampled data that a row security policy intended to hide.
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 could craft a leaky operator that bypassed view
access control lists (ACLs) and bypassed row security policies in
partitioning or table inheritance hierarchies. Reachable statistics data
notably included histograms and most- common-values lists. CVE-2017-7484
and CVE-2019-10130 intended to close this class of vulnerability, but
this gap remained. Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19,
and 13.22 are affected.
CVE-2025-8714: PostgreSQL pg_dump lets superuser of origin server execute
arbitrary code in psql client
Untrusted data inclusion in pg_dump in PostgreSQL allows a malicious
superuser of the origin server to inject arbitrary code for restore-time
execution as the client operating system account running psql to restore
the dump, via psql meta-commands. pg_dumpall is also affected. pg_restore
is affected when used to generate a plain-format dump. This is similar to
MySQL CVE-2024-21096. Versions before PostgreSQL 17.6, 16.10, 15.14,
14.19, and 13.22 are affected.
CVE-2025-8715: PostgreSQL pg_dump newline in object name executes
arbitrary code in psql client and in restore target server
Improper neutralization of newlines in pg_dump in PostgreSQL allows a user
of the origin server to inject arbitrary code for restore-time execution
as the client operating system account running psql to restore the dump,
via psql meta-commands inside a purpose-crafted object name. The same
attacks can achieve SQL injection as a superuser of the restore target
server. pg_dumpall, pg_restore, and pg_upgrade are also affected.
Versions before PostgreSQL 17.6, 16.10, 15.14, 14.19, and 13.22 are affected.
Versions before 11.20 are unaffected. CVE-2012-0868 had fixed this class
of problem, but version 11.20 reintroduced it.
