PostgreSQL Bugs Let Remote Authenticated Users Deny Service and Gain Elevated Privileges
SecurityTracker Alert ID:  1036617
SecurityTracker URL:  http://securitytracker.com/id/1036617
CVE Reference:   CVE-2016-5423, CVE-2016-5424   (Links to External Site)
Date:  Aug 12 2016
Impact:   Denial of service via network, Disclosure of user information, Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Two vulnerabilities were reported in PostgreSQL. A remote authenticated user can cause the target service to crash or gain elevated privileges on the target system.

A remote authenticated user can submit specially crafted SQL statements containing CASE/WHEN commands to cause the target server to crash, disclose portions of server memory, or potentially execute arbitrary code [CVE-2016-5423].

A remote authenticated user with CREATEDB or CREATEROLE roles can create a specially crafted object name containing newlines, carriage returns, double quotes, or backslashes that will, when a superuser runs certain maintenance programs (e.g., pg_dumpall, pg_upgrade, vacuumdb, reindexdb, and clusterdb), grant the user superuser privileges [CVE-2016-5424].

Heikki Linnakangas and Nathan Bossart each reported one vulnerability.

Impact:   A remote authenticated user can cause the target service to crash.

A remote authenticated user with CREATEDB or CREATEROLE roles can obtain elevated privileges on the target system.

Solution:   The vendor has issued a fix (9.1.23, 9.2.18, 9.3.14, 9.4.9, 9.5.4).

The vendor advisory is available at:

https://www.postgresql.org/about/news/1688/

Vendor URL:  www.postgresql.org/about/news/1688/ (Links to External Site)
Cause:   Access control error, Input validation error
Underlying OS:  Linux (Any), UNIX (Any), Windows (Any)
