postgresql:10 security update

PostgreSQL is an advanced object-relational database management system (DBMS).

The following packages have been upgraded to a later upstream version:
postgresql (10.15).

Security Fix(es):

* postgresql: Reconnection can downgrade connection security settings
(CVE-2020-25694)

* postgresql: Multiple features escape "security restricted operation" sandbox
(CVE-2020-25695)

* postgresql: psql's \gset allows overwriting specially treated variables
(CVE-2020-25696)

listed in the References section.

CVE-2020-25694
A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10,
before 10.15, before 9.6.20 and before 9.5.24. If a client application that
creates additional database connections only reuses the basic connection
parameters while dropping security-relevant parameters, an opportunity for a
man-in-the-middle attack, or the ability to observe clear-text transmissions,
could exist. The highest threat from this vulnerability is to data
confidentiality and integrity as well as system availability.
CVE-2020-25695
A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10,
before 10.15, before 9.6.20 and before 9.5.24. An attacker having permission to
create non-temporary objects in at least one schema can execute arbitrary SQL
functions under the identity of a superuser. The highest threat from this
vulnerability is to data confidentiality and integrity as well as system
availability.
CVE-2020-25696
A flaw was found in the psql interactive terminal of PostgreSQL in versions
before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before
9.5.24. If an interactive psql session uses \gset when querying a compromised
server, the attacker can execute arbitrary code as the operating system account
running psql. The highest threat from this vulnerability is to data
confidentiality and integrity as well as system availability.
