PostgreSQL 11.x < 11.13 / 12.x < 12.8 / 13.x < 13.4 Memory Disclosure

medium Nessus Plugin ID 152683

Language:

Synopsis

The remote database server is affected by a memory disclosure vulnerability.

Description

The version of PostgreSQL installed on the remote host is 11 prior to 11.13, 12 prior to 12.8, or 13 prior to 13.4. As such, it is potentially affected by a memory disclosure vulnerability:

- 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. (CVE-2021-3677)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to PostgreSQL 11.13 / 12.8 / 13.4 or later
