Amazon Linux AMI : postgresql8 (ALAS-2012-82)

medium Nessus Plugin ID 69689

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The pg_dump utility inserted object names literally into comments in the SQL script it produces. An unprivileged database user could create an object whose name includes a newline followed by a SQL command.
This SQL command might then be executed by a privileged user during later restore of the backup dump, allowing privilege escalation.
(CVE-2012-0868)

When configured to do SSL certificate verification, PostgreSQL only checked the first 31 characters of the certificate's Common Name field. Depending on the configuration, this could allow an attacker to impersonate a server or a client using a certificate from a trusted Certificate Authority issued for a different name. (CVE-2012-0867)

CREATE TRIGGER did not do a permissions check on the trigger function to be called. This could possibly allow an authenticated database user to call a privileged trigger function on data of their choosing.
(CVE-2012-0866)

Solution

Run 'yum update postgresql8' to update your system.
