Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : PostgreSQL vulnerabilities (USN-4633-1)

high Nessus Plugin ID 142968

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4633-1 advisory.

 Peter Eisentraut discovered that PostgreSQL incorrectly handled connection security settings. Client applications could possibly be connecting with certain security parameters dropped, contrary to expectations. (CVE-2020-25694)

 Etienne Stalmans discovered that PostgreSQL incorrectly handled the security restricted operation sandbox.
 An authenticated remote attacker could possibly use this issue to execute arbitrary SQL functions as a superuser. (CVE-2020-25695)

 Nick Cleaton discovered that PostgreSQL incorrectly handled the \gset meta-command. A remote attacker with a compromised server could possibly use this issue to execute arbitrary code. (CVE-2020-25696)

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

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

Solution

Update the affected packages.
