PostgreSQL 10.x before 10.1, 9.6.x before 9.6.6, 9.5.x before 9.5.10, 9.4.x before 9.4.15, 9.3.x before 9.3.20, and 9.2.x before 9.2.24 runs under a non-root operating system account, and database superusers have effective ability to run arbitrary code under that system account. PostgreSQL provides a script for starting the database server during system boot. Packages of PostgreSQL for many operating systems provide their own, packager-authored startup implementations. Several implementations use a log file name that the database superuser can replace with a symbolic link. As root, they open(), chmod() and/or chown() this log file name. This often suffices for the database superuser to escalate to root privileges when root starts the server.

The remote NewStart CGSL host, running version MAIN 5.04, has postgresql packages installed that are affected by multiple vulnerabilities:

  - Privilege escalation flaws were found in the Red Hat     initialization scripts of PostgreSQL. An attacker with     access to the postgres user account could use these     flaws to obtain root access on the server machine.
    (CVE-2017-15097)

  - Privilege escalation flaws were found in the     initialization scripts of PostgreSQL. An attacker with     access to the postgres user account could use these     flaws to obtain root access on the server machine.
    (CVE-2017-12172)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

According to its self-reported version number, the remote Junos Space version is prior to 17.2R1. It is, therefore, affected by multiple vulnerabilities.

This update for postgresql94 fixes the following issues :

Security issues fixed :

  - CVE-2017-15098: Fix crash due to rowtype mismatch in     json(b)_populate_recordset() (bsc#1067844).

  - CVE-2017-12172: Start scripts permit database     administrator to modify root-owned files. This issue did     not affect SUSE (bsc#1062538).

Bug fixes :

  - Update to version 9.4.15

Security Fix(es) :

  - Privilege escalation flaws were found in the     initialization scripts of PostgreSQL. An attacker with     access to the postgres user account could use these     flaws to obtain root access on the server machine.
    (CVE-2017-12172, CVE-2017-15097)

Note: This patch drops the script privileges from root to the postgres user. Therefore, this update works properly only if the postgres user has write access to the postgres' home directory, such as the one in the default configuration (/var/lib/pgsql).

According to the versions of the postgresql packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

From Red Hat Security Advisory 2017:3402 :

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.

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

Security Fix(es) :

* Privilege escalation flaws were found in the initialization scripts of PostgreSQL. An attacker with access to the postgres user account could use these flaws to obtain root access on the server machine.
(CVE-2017-12172, CVE-2017-15097)

Note: This patch drops the script privileges from root to the postgres user. Therefore, this update works properly only if the postgres user has write access to the postgres' home directory, such as the one in the default configuration (/var/lib/pgsql).

Red Hat would like to thank the PostgreSQL project for reporting CVE-2017-12172. The CVE-2017-15097 issue was discovered by Pedro Barbosa (Red Hat) and the PostgreSQL project. Upstream acknowledges Antoine Scemama (Brainloop) as the original reporter of these issues.

Privilege escalation flaws were found in the initialization scripts of PostgreSQL. A remote attacker with access to the postgres user account could use these flaws to obtain root access on the server machine.( CVE-2017-12172)

Invalid json_populate_recordset or jsonb_populate_recordset function calls in PostgreSQL can crash the server or disclose a few bytes of server memory.(CVE-2017-15098)

INSERT ... ON CONFLICT DO UPDATE commands in PostgreSQL disclose table contents that the invoker lacks privilege to read. These exploits affect only tables where the attacker lacks full read access but has both INSERT and UPDATE privileges. Exploits bypass row level security policies and lack of SELECT privilege.(CVE-2017-15099)

Invalid json_populate_recordset or jsonb_populate_recordset function calls in PostgreSQL can crash the server or disclose a few bytes of server memory.(CVE-2017-15098)

The version of PostgreSQL installed on the remote host is 9.2.x prior to 9.2.24, 9.3.x prior to 9.3.20, 9.4.x prior to 9.4.15, 9.5.x prior to 9.5.10, 9.6.x prior to 9.6.6, or 10.x prior to 10.1. It is, therefore, affected by multiple vulnerabilities including a denial of service attack.
