EulerOS 2.0 SP5 : postgresql (EulerOS-SA-2022-1281)

high Nessus Plugin ID 158487

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the postgresql packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - A flaw was found in PostgreSQL versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If a client application that creates additional database connections only reuses the basic connection parameters while dropping security-relevant parameters, an opportunity for a man-in- the-middle attack, or the ability to observe clear-text transmissions, could exist. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
 (CVE-2020-25694)

 - 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)

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected postgresql packages.
