Bug 618462 – <dev-db/postgresql-{9.2.21,9.3.17,9.4.12,9.5.7}: multiple vulnerabilities (CVE-2017-{7484,7485,7486})

• Status: RESOLVED FIXED
• Product: Gentoo Security

[Description Agostino Sarubbo 2017-05-14 17:30:50 UTC]

From ${URL} :

Three security vulnerabilities have been closed by this release:

CVE-2017-7484: selectivity estimators bypass SELECT privilege checks
CVE-2017-7485: libpq ignores PGREQUIRESSL environment variable
CVE-2017-7486: pg_user_mappings view discloses foreign server passwords
The fix for CVE-2017-7486 applies to new databases, see the release notes for the procedure to apply the fix to an existing database.

Any user relying on the PGREQUIRESSL environment variable is encouraged to use the sslmode connection string option, as use of PGREQUIRESSL 
is deprecated. CVE-2017-7485 does not affect the 9.2 series. For more information on these issues and how they affect 
backwards-compatibility, see the Release Notes.


@maintainer(s): since the fixed package is already in the tree, please let us know if it is ready for the stabilization or not.

Here are the stabilization targets:

=app-eselect/eselect-postgresql-2.1 ~alpha ~amd64 ~arm ~arm64 ~hppa ~ia64 ~ppc ~ppc64 ~sparc ~x86
=dev-db/postgresql-9.2.21 ~alpha ~amd64 ~arm ~arm64 ~hppa ~ia64 ~ppc ~ppc64 ~sparc ~x86
=dev-db/postgresql-9.3.17 ~alpha ~amd64 ~arm ~arm64 ~hppa ~ia64 ~ppc ~ppc64 ~sparc ~x86
=dev-db/postgresql-9.4.12 ~alpha ~amd64 ~arm ~arm64 ~hppa ~ia64 ~ppc ~ppc64 ~sparc ~x86
=dev-db/postgresql-9.5.7 ~amd64 ~arm ~arm64 ~hppa ~ia64 ~ppc ~ppc64 ~sparc ~x86

While app-eselect/eselect-postgresql-2.1 was just added today, it was to fix the only bug open against 2.0 (which is the minimum these ebuilds require) since it was introduced a over a month ago.

As has been mentioned on previous bugs, 9.5 on up is excluded from Alpha stabilization given upstream dropping support specific to that architecture.

CVE-2017-7486 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-7486):
  PostgreSQL versions 8.4 - 9.6 are vulnerable to information leak in
  pg_user_mappings view which discloses foreign server passwords to any user
  having USAGE privilege on the associated foreign server.

CVE-2017-7485 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-7485):
  In PostgreSQL 9.3.x before 9.3.17, 9.4.x before 9.4.12, 9.5.x before 9.5.7,
  and 9.6.x before 9.6.3, it was found that the PGREQUIRESSL environment
  variable was no longer enforcing a SSL/TLS connection to a PostgreSQL
  server. An active Man-in-the-Middle attacker could use this flaw to strip
  the SSL/TLS protection from a connection between a client and a server.

CVE-2017-7484 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2017-7484):
  It was found that some selectivity estimation functions in PostgreSQL before
  9.2.21, 9.3.x before 9.3.17, 9.4.x before 9.4.12, 9.5.x before 9.5.7, and
  9.6.x before 9.6.3 did not check user privileges before providing
  information from pg_statistic, possibly leaking information. An unprivileged
  attacker could use this flaw to steal some information from tables they are
  otherwise not allowed to access.
