"This update for postgresql96 to 9.6.10 fixes the following issues :

These security issues were fixed :

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)

For addition details please see
https://www.postgresql.org/docs/current/static/release-9-6-10.html

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."
