PostgreSQL — свободная объектно-реляционная система управления базами данных.

A flaw was found in PostgreSQL's "ALTER ... DEPENDS ON EXTENSION", where sub-commands did not perform authorization checks. An authenticated attacker could use this flaw in certain configurations to perform drop objects such as function, triggers, et al., leading to database corruption. This issue affects PostgreSQL versions before 12.2, before 11.7, before 10.12 and before 9.6.17.

PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 does not properly handle errors while reading a protocol message, which allows remote attackers to conduct SQL injection attacks via crafted binary data in a parameter and causing an error, which triggers the loss of synchronization and part of the protocol message to be treated as a new message, as demonstrated by causing a timeout or query cancellation.

PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9. ...

Multiple buffer overflows in contrib/pgcrypto in PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 allow remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via unspecified vectors.

Stack-based buffer overflow in the *printf function implementations in PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1, when running on a Windows system, allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via a floating point number with a large precision, as demonstrated by using the to_char function.

The to_char function in PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 allows remote authenticated users to cause a denial of service (crash) or possibly execute arbitrary code via a (1) large number of digits when processing a numeric formatting template, which triggers a buffer over-read, or (2) crafted timestamp formatting template, which triggers a buffer overflow.

The to_char function in PostgreSQL before 9.0.19, 9.1.x before 9.1.15, ...

PostgreSQL before 9.0.19, 9.1.x before 9.1.15, 9.2.x before 9.2.10, 9.3.x before 9.3.6, and 9.4.x before 9.4.1 allows remote authenticated users to obtain sensitive column values by triggering constraint violation and then reading the error message.
