Synopsis

The remote database server is affected by multiple vulnerabilities.

Description

The version of PostgreSQL installed on the remote host is 9.0.x prior to 9.0.23, 9.1.x prior to 9.1.19, 9.2.x prior to 9.2.14, 9.3.x prior to 9.3.10, or 9.4.x prior to 9.4.5. It is, therefore, affected by multiple vulnerabilities :

 - A denial of service vulnerability exists due to an unspecified flaw in the crypt() function. An authenticated, remote attacker can exploit this to cause a memory leak, resulting in a denial of service condition. (CVE-2015-5288)

 - A denial of service vulnerability exists due to improper validation of user-supplied JSON input. An authenticated, remote attacker can exploit this, via specially crafted JSON input, to cause the server to crash. (CVE-2015-5289)

 - A denial of service vulnerability exists due to a flaw that is triggered when a function is executed in an outer-subtransaction cursor. An authenticated, remote attacker can exploit this to cause a denial of service condition.

 - Multiple stack overflow conditions exist due to improper validation of user-supplied input when handling input to record types, range types, json, jsonb, tsquery, ltxtquery and query_int. An authenticated, remote attacker can exploit this to cause a denial of service condition and potentially remote code execution.

 - An information disclosure vulnerability exists due to world-readable permissions granted to temporary files that are created during a pg_dump with tar-format output. A local attacker can exploit this disclose sensitive information.

 - An overflow condition exists due to improper validation of user-supplied input when handling SIMILAR TO and LIKE matching regular expressions. An authenticated, remote attacker can exploit this to cause a stack overflow, resulting in a denial of service condition.

Solution

Upgrade to PostgreSQL 9.0.23 / 9.1.19 / 9.2.14 / 9.3.10 / 9.4.5 or later.
