-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: postgresql security update Advisory ID: RHSA-2017:2728-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:2728 Issue date: 2017-09-14 CVE Names: CVE-2017-7546 CVE-2017-7547 ===================================================================== 1. Summary: An update for postgresql is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: PostgreSQL is an advanced object-relational database management system (DBMS). The following packages have been upgraded to a later upstream version: postgresql (9.2.23). (BZ#1484639, BZ#1484647) Security Fix(es): * It was found that authenticating to a PostgreSQL database account with an empty password was possible despite libpq's refusal to send an empty password. A remote attacker could potentially use this flaw to gain access to database accounts with empty passwords. (CVE-2017-7546) * An authorization flaw was found in the way PostgreSQL handled access to the pg_user_mappings view on foreign servers. A remote, authenticated attacker could potentially use this flaw to retrieve passwords from the user mappings defined by the foreign server owners without actually having the privileges to do so. (CVE-2017-7547) Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Ben de Graaff, Jelte Fennema, and Jeroen van der Ham as the original reporters of CVE-2017-7546; and Jeff Janes as the original reporter of CVE-2017-7547. 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/): 1477184 - CVE-2017-7546 postgresql: Empty password accepted in some authentication methods 1477185 - CVE-2017-7547 postgresql: pg_user_mappings view discloses passwords to users lacking server privileges 6.
