Уязвимость компонента core server системы управления базами данных PostgreSQL, позволяющая нарушителю оказать влияние на целостность, доступность и конфиденциальность данных

Уязвимость реализации мета-команды «gset» системы управления базами данных PostgreSQL, позволяющая нарушителю выполнить произвольный код

Уязвимость компонента client системы управления базами данных PostgreSQL, позволяющая нарушителю реализовать атаку типа «человек посередине»

Уязвимость системы управления базами данных PostgreSQL, связанная с ошибками механизмов безопасности, позволяющая нарушителю получить значения столбцов из сообщения об ошибке (без привилегии SELECT)

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.

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. An attacker having permission to create non-temporary objects in at least one schema can execute arbitrary SQL functions under the identity of a superuser. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A flaw was found in the psql interactive terminal of PostgreSQL in versions before 13.1, before 12.5, before 11.10, before 10.15, before 9.6.20 and before 9.5.24. If an interactive psql session uses \gset when querying a compromised server, the attacker can execute arbitrary code as the operating system account running psql. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

An information leak was discovered in postgresql in versions before 13.2, before 12.6 and before 11.11. A user having UPDATE permission but not SELECT permission to a particular column could craft queries which, under some circumstances, might disclose values from that column in error messages. An attacker could use this flaw to obtain information stored in a column they are allowed to write but not read.
