Virtuozzo 6 : postgresql / postgresql-contrib / postgresql-devel / etc (VZLSA-2017-2860)

critical Nessus Plugin ID 119231


The remote Virtuozzo host is missing a security update.


An update for postgresql is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* It was found that authenticating to a PostgreSQL database account with an empty password was possible despite libpq's refusal to send an empty password. A remote attacker could potentially use this flaw to gain access to database accounts with empty passwords. (CVE-2017-7546)

Red Hat would like to thank the PostgreSQL project for reporting this issue. Upstream acknowledges Ben de Graaff, Jelte Fennema, and Jeroen van der Ham as the original reporters.

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected postgresql / postgresql-contrib / postgresql-devel / etc package.
