Synopsis
========

Multiple vulnerabilities have been found in PostgreSQL, the worst which
could lead to privilege escalation.

Background
==========

PostgreSQL is an open source object-relational database management
system.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  dev-db/postgresql             < 10.5               >= 9.3.24:9.3
                                                        >= 9.4.19:9.4
                                                        >= 9.5.14:9.5
                                                        >= 9.6.10:9.6
                                                           >= 10.5:10

Description
===========

Multiple vulnerabilities have been discovered in PostgreSQL. Please
review the referenced CVE identifiers for details.

In addition it was discovered that Gentoo's PostgreSQL installation
suffered from a privilege escalation vulnerability due to a runscript
which called OpenRC's checkpath() on a user controlled path and allowed
user running PostgreSQL to kill arbitrary processes via PID file
manipulation.

Impact
======

A remote attacker could bypass certain client-side connection security
features, read arbitrary server memory or alter certain data.

In addition, a local attacker could gain privileges or cause a Denial
of Service condition by  killing arbitrary processes.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PostgreSQL users up to 9.3 should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose
 ">=dev-db/postgresql-9.3.24:9.3"

All PostgreSQL 9.4 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose
 ">=dev-db/postgresql-9.4.19:9.4"

All PostgreSQL 9.5 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose
 ">=dev-db/postgresql-9.5.14:9.5"

All PostgreSQL 9.6 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose
 ">=dev-db/postgresql-9.6.10:9.6"

All PostgreSQL 10 users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=dev-db/postgresql-10.5:10"
