-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: rh-postgresql95-postgresql security update Advisory ID: RHSA-2017:2677-01 Product: Red Hat Software Collections Advisory URL: https://access.redhat.com/errata/RHSA-2017:2677 Issue date: 2017-09-12 CVE Names: CVE-2017-7546 CVE-2017-7547 CVE-2017-7548 ===================================================================== 1. Summary: An update for rh-postgresql95-postgresql is now available for Red Hat Software Collections. 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 Software Collections for Red Hat Enterprise Linux Server (v. 6) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 7) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.7) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 7.3) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 6) - x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (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: rh-postgresql95-postgresql (9.5.9). (BZ#1484637, BZ#1484642, BZ#1484648) 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) * An authorization flaw was found in the way PostgreSQL handled large objects. A remote, authenticated attacker with no privileges on a large object could potentially use this flaw to overwrite the entire content of the object, thus resulting in denial of service. (CVE-2017-7548) 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; Jeff Janes as the original reporter of CVE-2017-7547; and Chapman Flack as the original reporter of CVE-2017-7548. 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.
