https://notcve.org/view.php?id=CVE-2021-23214
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. Cuando el servidor está configurado para usar la autenticación confiable con un requisito de clientcert o para usar la autenticación de cert, un atacante de tipo man-in-the-middle puede inyectar consultas SQL arbitrarias cuando es establecida una conexión por primera vez, a pesar del uso de la verificación y el cifrado del certificado SSL It was found that a PostgreSQL server could accept plain text data during the establishment of an SSL connection. When a user is requesting a certificate based authentication, an active Person in the Middle could use this flaw in order to inject arbitrary SQL commands. • https://bugzilla.redhat.com/show_bug.cgi?id=2022666 https://git.postgresql.org/gitweb/?p=postgresql.git%3Ba=commit%3Bh=28e24125541545483093819efae9bca603441951 https://github.com/postgres/postgres/commit/28e24125541545483093819efae9bca603441951 https://security.gentoo.org/glsa/202211-04 https://www.postgresql.org/support/security/CVE-2021-23214 https://access.redhat.com/security/cve/CVE-2021-23214 • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •

https://notcve.org/view.php?id=CVE-2021-3677
A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. • https://bugzilla.redhat.com/show_bug.cgi?id=2001857 https://security.gentoo.org/glsa/202211-04 https://security.netapp.com/advisory/ntap-20220407-0008 https://www.postgresql.org/support/security/CVE-2021-3677 https://access.redhat.com/security/cve/CVE-2021-3677 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se ha encontrado un fallo en postgresql en las versiones anteriores a 13.3, versiones anteriores a 12.7, versiones anteriores a 11.12, versiones anteriores a 10.17 y versiones anteriores a 9.6.22. Cuando se modifican determinados valores de matrices SQL, una falta de comprobación de límites permite a usuarios autentificados de la base de datos escribir bytes arbitrarios en una amplia zona de la memoria del servidor. • https://bugzilla.redhat.com/show_bug.cgi?id=1956876 https://security.gentoo.org/glsa/202211-04 https://security.netapp.com/advisory/ntap-20210713-0004 https://www.postgresql.org/support/security/CVE-2021-32027 https://access.redhat.com/security/cve/CVE-2021-32027 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-190: Integer Overflow or Wraparound •
