Red Hat Security Advisory 2015-2078-01
Posted Nov 19, 2015
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2015-2078-01 - PostgreSQL is an advanced object-relational database management system. 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. 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.

3. 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 postgresql service is running, it will
be automatically restarted after installing this update.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

For details on how to apply this update, refer to:

https://access.redhat.com/articles/11258
