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 9.1.23, 9.2.x prior to 9.2.18, 9.3.x prior to 9.3.14, 9.4.x prior to 9.4.9, or 9.5.x prior to 9.5.4. It is, therefore, affected by the following vulnerabilities :- A denial of service vulnerability exists that allows an authenticated, remote attacker to crash the database via specially crafted nested CASE expressions.
(CVE-2016-5423)
- A flaw exists that is triggered during the handling of database and role names with embedded special characters. An unauthenticated, remote attacker can exploit this to execute arbitrary code during administrative operations such as pg_dumpall.
(CVE-2016-5424)
- A denial of service vulnerability exists in the pg_get_expr() function that is triggered during the handling of inconsistent values. An authenticated, remote attacker can exploit this to crash the database.
- An overflow condition exists in the to_number() function due to improper validation of user-supplied input. An authenticated, remote attacker can exploit this to cause a denial of service condition.
Solution
Upgrade to PostgreSQL version 9.1.23 / 9.2.18 / 9.3.14 / 9.4.9 / 9.5.4 or later.See Also
