An update that fixes one vulnerability is now available.

Description:

This update for postgresql95 fixes the following issues:

– Update to PostgreSQL 9.5.13:
* https://www.postgresql.org/docs/9.5/static/release-9-5-13.html A
dump/restore is not required for those running 9.5.X. However, if the
function marking mistakes mentioned belowpg_logfile_rotate affect you,
you will want to take steps to correct your database catalogs.

The functions query_to_xml, cursor_to_xml, cursor_to_xmlschema,
query_to_xmlschema, and query_to_xml_and_xmlschema should be marked
volatile because they execute user-supplied queries that might contain
volatile operations. They were not, leading to a risk of incorrect query
optimization. This has been repaired for new installations by correcting
the initial catalog data, but existing installations will continue to
contain the incorrect markings. Practical use of these functions seems to
pose little hazard, but in case of trouble, it can be fixed by manually
updating these functions’ pg_proc entries, for example: ALTER FUNCTION
pg_catalog.query_to_xml(text, boolean, boolean, text) VOLATILE. (Note that
that will need to be done in each database of the installation.) Another
option is to pg_upgrade the database to a version containing the corrected
initial data.

Security issue 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)
