Synopsis

The remote database server is affected by multiple vulnerabilities.

Description

The version of PostgreSQL installed on the remote host is 9.2.x prior to 9.2.20, 9.3.x prior to 9.3.16, 9.4.x prior to 9.4.11, 9.5.x prior to 9.5.6, or 9.6.x prior to 9.6.2. It is, therefore, affected by multiple vulnerabilities :

- An off-by-one buffer overflow condition exists in the quote_literal_cstr() function due to improper validation of certain input when it is encased entirely in single quotes or backslashes. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.

- A flaw exists when handling multiple concurrent calls of the pg_strat_backup() and pg_stop_backup() functions.
An unauthenticated, remote attacker can exploit this to cause a denial of service condition.

- An off-by-one buffer overflow condition exists due to improper validation of certain input when handling a filename supplied to ecpg that ends with a dot. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or potentially the execution of arbitrary code.

Solution

Upgrade to PostgreSQL version 9.2.20 / 9.3.16 / 9.4.11 / 9.5.6 / 9.6.2 or later.
