The version of PostgreSQL installed on the remote host is 9.2.x prior to 9.2.21, 9.3.x prior to 9.3.17, 9.4.x prior to 9.4.12, 9.5.x prior to 9.5.7, or 9.6.x prior to 9.6.3. It is, therefore, affected by multiple vulnerabilities :

  - A information disclosure vulnerability exists in     unspecified selectivity estimation functions due to     improper checking of user privileges before providing     information from pg_statistics. An authenticated, remote     attacker can exploit this to disclose potentially     sensitive information from restricted tables.
    (CVE-2017-7484)

  - A flaw exists because the PGREQUIRESSL environment     variable setting is not properly honored, which results     in a failure to require appropriate SSL/TLS connections.
    A man-in-the-middle attacker can exploit this to cause     an insecure, non-SSL/TLS connection between a client and     and a server. Note that version 9.2.x is not affected by     this vulnerability. (CVE-2017-7485)

  - A information disclosure vulnerability exists in the     pg_user_mappings view that allows access to user     mappings which may contain passwords that have persisted     from the CREATE USER MAPPING command. An authenticated,     remote attacker who has USAGE privilege on the     associated foreign server can exploit this to disclose     foreign server passwords. (CVE-2017-7486)

Selectivity estimators bypass SELECT privilege checks

It was found that some selectivity estimation functions 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. (CVE-2017-7484)

libpq ignores PGREQUIRESSL environment variable

It was found that the PGREQUIRESSL 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-2017-7485)

pg_user_mappings view discloses foreign server passwords

It was found that the pg_user_mappings view from postgresql could disclose information about user mappings to a foreign database to unprivileged users. An authenticated attacker with USAGE privilege for this mapping could, when querying the view, obtain user mapping data, such as the username and password used to connect to the foreign database. (CVE-2017-7486)

This update for postgresql93 fixes the following issues :

The PostgreSQL package was updated to 9.3.17, bringing various bug and security fixes.

Security fixes :

  - CVE-2017-7486: Restrict visibility of     pg_user_mappings.umoptions, to protect passwords stored     as user mapping options. (bsc#1037624)

An update for rh-postgresql95-postgresql is now available for Red Hat Satellite 5.8 and Red Hat Satellite 5.8 ELS.

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.

This update applies only to Satellite 5.8 instances using either embedded or managed PostgreSQL databases.

There are manual steps required in order to finish the migration from postgresql92-postgresql to rh-postgresql95-postgresql. If these steps are not undertaken, the affected Satellite will continue to use PostgreSQL 9.2.

postgresql92-postgresql will be upgraded automatically to rh-postgresql95-postgresql as part of an upgrade to Satellite 5.8.

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

Security Fix(es) :

* It was found that some selectivity estimation functions did not check user privileges before providing information from pg_statistic, possibly leaking information. A non-administrative database user could use this flaw to steal some information from tables they are otherwise not allowed to access. (CVE-2017-7484)

* It was discovered that the PostgreSQL client library (libpq) did not enforce the use of TLS/SSL for a connection to a PostgreSQL server when the PGREQUIRESSL environment variable was set. An 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-2017-7485)

* It was found that the pg_user_mappings view could disclose information about user mappings to a foreign database to non-administrative database users. A database user with USAGE privilege for this mapping could, when querying the view, obtain user mapping data, such as the username and password used to connect to the foreign database. (CVE-2017-7486)

Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Robert Haas as the original reporter of CVE-2017-7484; Daniel Gustafsson as the original reporter of CVE-2017-7485; and Andrew Wheelwright as the original reporter of CVE-2017-7486.

Several vulnerabilities have been found in the PostgreSQL database system :

  - CVE-2017-7484     Robert Haas discovered that some selectivity estimators     did not validate user privileges which could result in     information disclosure.

  - CVE-2017-7485     Daniel Gustafsson discovered that the PGREQUIRESSL     environment variable did no longer enforce a TLS     connection.

  - CVE-2017-7486     Andrew Wheelwright discovered that user mappings were     insufficiently restricted.
