Synopsis

The remote database server is affected by a denial of service vulnerability.

Description

The version of PostgreSQL installed on the remote host is 9.1.x prior to 9.1.24, 9.2.x prior to 9.2.19, 9.3.x prior to 9.3.15, 9.4.x prior to 9.4.10, 9.5.x prior to 9.5.5, or 9.6.x prior to 9.6.1. It is, therefore, affected by a denial of service vulnerability due to a use-after-free error when executing aggregate functions using DISTINCT. An unauthenticated, remote attacker can exploit this to deference already freed memory, resulting in crashing the database.

Solution

Upgrade to PostgreSQL version 9.1.24 / 9.2.19 / 9.3.15 / 9.4.10 / 9.5.5 / 9.6.1 or later.
