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. PostgreSQL is an advanced object-relational database management system (DBMS). The following packages have been upgraded to a newer upstream version: postgresql (9.2.18). Security Fix(es) : * A flaw was found in the way PostgreSQL server handled certain SQL statements containing CASE/WHEN commands. A remote, authenticated attacker could use a specially crafted SQL statement to cause PostgreSQL to crash or disclose a few bytes of server memory or possibly execute arbitrary code. (CVE-2016-5423) * A flaw was found in the way PostgreSQL client programs handled database and role names containing newlines, carriage returns, double quotes, or backslashes. By crafting such an object name, roles with the CREATEDB or CREATEROLE option could escalate their privileges to superuser when a superuser next executes maintenance with a vulnerable client program. (CVE-2016-5424) Red Hat would like to thank the PostgreSQL project for reporting these issues. Upstream acknowledges Heikki Linnakangas as the original reporter of CVE-2016-5423; and Nathan Bossart as the original reporter of CVE-2016-5424.

It is, therefore, affected by the following vulnerabilities : - A denial of service vulnerability exists that allows an authenticated, remote attacker to crash the database via specially crafted nested CASE expressions. (CVE-2016-5423) - A flaw exists that is triggered during the handling of database and role names with embedded special characters. An unauthenticated, remote attacker can exploit this to execute arbitrary code during administrative operations such as pg_dumpall. (CVE-2016-5424) - A denial of service vulnerability exists in the pg_get_expr() function that is triggered during the handling of inconsistent values. An authenticated, remote attacker can exploit this to crash the database. - An overflow condition exists in the to_number() function due to improper validation of user-supplied input. An authenticated, remote attacker can exploit this to cause a denial of service condition. last seen 2020-06-01 modified 2020-06-02 plugin id 93050 published 2016-08-19 reporter This script is Copyright (C) 2016-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/93050 title PostgreSQL 9.1.x < 9.1.23 / 9.2.x < 9.2.18 / 9.3.x < 9.3.14 / 9.4.x < 9.4.9 / 9.5.x < 9.5.4 Multiple Vulnerabilities NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-201701-33.NASL description The remote host is affected by the vulnerability described in GLSA-201701-33 (PostgreSQL: Multiple vulnerabilities) Multiple vulnerabilities have been discovered in PostgreSQL.
