Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2817 advisory.

- A man-in-the-middle attacker can inject false responses to the client's first few queries, despite the use of SSL certificate verification and encryption. (CVE-2021-23222)

- When the server is configured to use trust authentication with a clientcert requirement or to use cert authentication, a man-in-the-middle attacker can inject arbitrary SQL queries when a connection is first established, despite the use of SSL certificate verification and encryption. (CVE-2021-23214)

Note that Nessus has not tested for this issue but has instead relied only on the application's self- reported version number.

Solution

Upgrade the postgresql-9.6 packages.

For Debian 9 stretch, these problems have been fixed in version 9.6.24-0+deb9u1.
