Ubuntu 22.04 LTS / 23.10 / 24.04 LTS : PostgreSQL vulnerability (USN-6802-1)

low Nessus Plugin ID 198154

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 22.04 LTS / 23.10 / 24.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6802-1 advisory.

 Lukas Fittl discovered that PostgreSQL incorrectly performed authorization in the built-in pg_stats_ext and pg_stats_ext_exprs views. An unprivileged database user can use this issue to read most common values and other statistics from CREATE STATISTICS commands of other users.

 NOTE: This update will only fix fresh PostgreSQL installations. Current PostgreSQL installations will remain vulnerable to this issue until manual steps are performed. Please see the instructions in the changelog located at /usr/share/doc/postgresql-*/changelog.Debian.gz after the updated packages have been installed, or in the PostgreSQL release notes located here:

 https://www.postgresql.org/docs/16/release-16-3.html https://www.postgresql.org/docs/15/release-15-7.html https://www.postgresql.org/docs/14/release-14-12.html

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

Solution

Update the affected packages.
