openSUSE Security Update : postgresql10 (openSUSE-2018-955)

Medium Nessus Plugin ID 112269

Synopsis

The remote openSUSE host is missing a security update.

Description

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).

This update was imported from the SUSE:SLE-15:Update update project.

Solution

Update the affected postgresql10 packages.
