Summary

PostgreSQL is prone to a memory disclosure vulnerability.

Insight

Insight

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. However, undiscovered variants of the attack may be independent of that setting.

Affected Software

Affected Software

PostgreSQL 11.0 through 11.12, 12.0 through 12.7 and 13.0 through 13.3.

Detection Method

Detection Method

Checks if a vulnerable version is present on the target host.

Solution

Solution

Update to version 11.13, 12.8, 13.4 or later.
