Se han formado actualizaciones correctivas para todas las ramas compatibles de PostgreSQL: 14.1, 13.5, 12.9, 11.14, 10.19 y 9.6.24. La versi\u00f3n 9.6.24 ser\u00e1 la \u00faltima actualizaci\u00f3n para la rama 9.6, cuya soporte ha finalizado. Las actualizaciones para la rama 10 se formar\u00e1n hasta noviembre de 2022, la 11 hasta noviembre de 2023, la 12 hasta noviembre de 2024, la 13 hasta noviembre de 2025 y la 14 hasta noviembre de 2026. <\/p>\n

En las nuevas versiones se han propuesto m\u00e1s de 40 correcciones y se han solucionado dos vulnerabilidades (CVE-2021-23214, CVE-2021-23222) en el proceso del servidor y en la biblioteca cliente libpq. Las vulnerabilidades permiten que un atacante se infiltre en un canal de comunicaci\u00f3n cifrado a trav\u00e9s de un ataque MITM. El ataque no requiere de un certificado v\u00e1lido. SSL<\/a>-certificado y puede llevarse a cabo contra sistemas que requieren autenticaci\u00f3n del cliente mediante certificado. En el contexto del servidor, el ataque permite la sustituci\u00f3n de su propia consulta SQL en el momento de establecer la conexi\u00f3n cifrada entre el cliente y el servidor de PostgreSQL. En el contexto de libpq, la vulnerabilidad permite que un atacante devuelva una respuesta ficticia del servidor al cliente. En conjunto, estas vulnerabilidades permiten extraer informaci\u00f3n sobre contrase\u00f1as u otros datos confidenciales del cliente, que se transmiten en las primeras etapas de la conexi\u00f3n. <\/p>\n

Adem\u00e1s, se puede mencionar la publicaci\u00f3n de una nueva versi\u00f3n del servidor proxy Odyssey 1.2 por parte de Yandex, dise\u00f1ada para mantener un pool de conexiones abiertas a bases de datos PostgreSQL y organizar la ruta de solicitudes. Odyssey soporta la ejecuci\u00f3n de m\u00faltiples procesos de trabajo con manejadores multihilo, dirigi\u00e9ndose adem\u00e1s servidor<\/a> a la reconexi\u00f3n del cliente, con la posibilidad de vincular pools de conexiones a usuarios y bases de datos. El c\u00f3digo est\u00e1 escrito en C y se distribuye bajo la licencia BSD. <\/p>\n

En la nueva versi\u00f3n de Odyssey se ha a\u00f1adido una protecci\u00f3n para bloquear la sustituci\u00f3n de datos tras el acuerdo de la sesi\u00f3n SSL (lo que permite bloquear ataques utilizando las vulnerabilidades mencionadas CVE-2021-23214 y CVE-2021-23222). Se ha implementado soporte para PAM y LDAP. Se ha a\u00f1adido integraci\u00f3n con el sistema de monitoreo Prometheus. Se ha mejorado el c\u00e1lculo de los par\u00e1metros estad\u00edsticos para tener en cuenta el tiempo de ejecuci\u00f3n de transacciones y consultas.
