Description

PostgreSQL is an advanced object-relational database management system (DBMS).

A memory leak error was discovered in the crypt() function of the pgCrypto extension. An authenticated attacker could possibly use this flaw to disclose a limited amount of the server memory. (CVE-2015-5288)

A stack overflow flaw was discovered in the way the PostgreSQL core server processed certain JSON or JSONB input. An authenticated attacker could possibly use this flaw to crash the server backend by sending specially crafted JSON or JSONB input. (CVE-2015-5289)

Please note that SSL renegotiation is now disabled by default. For more information, please refer to PostgreSQL's 2015-10-08 Security Update Release notes, linked to in the References section.

All PostgreSQL users are advised to upgrade to these updated packages, which correct these issues. If the postgresql92-postgresql service is running, it will be automatically restarted after installing this update.
