Use of a Broken or Risky Cryptographic Algorithm

Affecting postgresql-9.6 package, versions <9.6.20-0+deb9u1

Overview

Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm. 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.

Remediation

Upgrade postgresql-9.6 to version or higher.
