"This update for postgresql10 fixes the following issues :

PostgreSQL 10 was updated to 10.5 :

https://www.postgresql.org/about/news/1851/

https://www.postgresql.org/docs/current/static/release-10-5.html

A dump/restore is not required for those running 10.X. However, if you
use the adminpack extension, you should update it as per the first
changelog entry below. Also, if the function marking mistakes
mentioned in the second and third changelog entries below affect you,
you will want to take steps to correct your database catalogs.

Security issues fixed: CVE-2018-1115: Remove public execute privilege
from contrib/adminpack's pg_logfile_rotate() function
pg_logfile_rotate() is a deprecated wrapper for the core function
pg_rotate_logfile(). When that function was changed to rely on SQL
privileges for access control rather than a hard-coded superuser
check, pg_logfile_rotate() should have been updated as well, but the
need for this was missed. Hence, if adminpack is installed, any user
could request a logfile rotation, creating a minor security issue.
After installing this update, administrators should update adminpack
by performing ALTER EXTENSION adminpack UPDATE in each database in
which adminpack is installed (bsc#1091610).

CVE-2018-10915: libpq failed to properly reset its internal state
between connections. If an affected version of libpq was used with
'host' or 'hostaddr' connection parameters from untrusted input,
attackers could have bypassed client-side connection security
features, obtain access to higher privileged connections or
potentially cause other impact SQL injection, by causing the
PQescape() functions to malfunction (bsc#1104199)

CVE-2018-10925: Add missing authorization check on certain statements
involved with 'INSERT ... ON CONFLICT DO UPDATE'. An attacker with
'CREATE TABLE' privileges could have exploited this to read arbitrary
bytes server memory. If the attacker also had certain 'INSERT' and
limited 'UPDATE' privileges to a particular table, they could have
exploited this to update other columns in the same table
(bsc#1104202).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
