PostgreSQL 13.4, 12.8, 11.13, 10.18, 9.6.23 Security Issues 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. |

pkgsrc
pkgsrc is a framework for building software for a variety of UNIX-like systems.
It produces binary packages, which can be managed with tools such as
pkgin. pkgsrc is highly configurable, supporting
building packages for an arbitrary installation prefix (the default is
/usr/pkg), allowing multiple branches to coexist on one machine, a
build options framework, and a compiler transformation framework, among
other advanced features. Unprivileged use and installation is also supported.
pkgsrc is the default package manager for NetBSD and SmartOS. It's also supported as a first-class option in OmniOS CE and Oasis Linux.
Bootstrapping
To use pkgsrc on operating systems other than NetBSD, you first need to bootstrap:
cd pkgsrc/bootstrap
./bootstrap
Note that this is only for the most simple case, using pkgsrc's defaults.
Please consult bootstrap/README and bootstrap/README.OS for detailed
information about bootstrapping.
Building packages
cd pkgsrc/category/package-name
$PREFIX/bin/bmake install
Where $PREFIX is where you've chosen to install packages
(typically /usr/pkg)
On NetBSD, bmake is simply the built-in make tool.
To build packages in bulk, tools such as pkgtools/pbulk and
pkgtools/pkg_comp can be used.
