1. Summary:

An update for rh-postgresql95-postgresql is now available for Red Hat
Software Collections.

3. Description:

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

Security Fix(es):

* Privilege escalation flaws were found in the initialization scripts of
PostgreSQL. An attacker with access to the postgres user account could use
these flaws to obtain root access on the server machine. (CVE-2017-12172,
CVE-2017-15097)

Note: This patch drops the script privileges from root to the postgres
user. Therefore, we dropped the --new-systemd-unit option for security
reasons. Please use the root-only script postgresql-new-systemd-unit.

Red Hat would like to thank the PostgreSQL project for reporting
CVE-2017-12172. The CVE-2017-15097 issue was discovered by Pedro Barbosa
(Red Hat) and the PostgreSQL project. Upstream acknowledges Antoine Scemama
(Brainloop) as the original reporter of these issues.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

If the postgresql service is running, it will be automatically restarted
after installing this update.

5. Bugs fixed (https://bugzilla.redhat.com/):

1498394 - CVE-2017-12172 postgresql: Start scripts permit database administrator to modify root-owned files
1508985 - CVE-2017-15097 postgresql: Start scripts permit database administrator to modify root-owned files
