PostgreSQL 9.1.x < 9.1.20 / 9.2.x < 9.2.15 / 9.3.x < 9.3.11 / 9.4.x < 9.4.6 / 9.5.x < 9.5.1 Multiple Vulnerabilities

Synopsis

The remote database server is affected by multiple vulnerabilities.

Description

The version of PostgreSQL installed on the remote host is 9.1.x prior to 9.1.20, 9.2.x prior to 9.2.15, 9.3.x prior to 9.3.11, 9.4.x prior to 9.4.6, or 9.5.x prior to 9.5.1. It is, therefore, affected by the following vulnerabilities :

- An integer overflow condition exists due to improper validation of user-supplied input when handling regular expressions. An authenticated, remote attacker can exploit this, via a large Unicode character range in a regular expression, to cause a denial of service condition or the execution of arbitrary code.
(CVE-2016-0773)

- A privilege escalation vulnerability exists due to a flaw in the init_custom_variable() function that is triggered during the handling of PL/Java. An authenticated, remote attacker can exploit this to gain elevation privileges. (CVE-2016-0766)

Solution

Upgrade to PostgreSQL version 9.1.20 / 9.2.15 / 9.3.11 / 9.4.6 / 9.5.1 or later.
