Ubuntu 20.04 LTS : PostgreSQL vulnerability (USN-4735-1)

medium Nessus Plugin ID 146494

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4735-1 advisory.

 Heikki Linnakangas discovered that PostgreSQL incorrectly leaked values of denied columns when handling certain errors. A remote attacker could possibly use this issue to obtain sensitive information.

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.
