Ubuntu 20.04 LTS / 22.04 LTS / 23.04 : PostgreSQL vulnerabilities (USN-6296-1)

high Nessus Plugin ID 179929

Language:

Synopsis

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

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS / 23.04 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6296-1 advisory.

 It was discovered that PostgreSQL incorrectly handled certain extension script substitutions. An attacker having database-level CREATE privileges can use this issue to execute arbitrary code as the bootstrap superuser. (CVE-2023-39417)

 It was discovered that PostgreSQL incorrectly handled the MERGE command. A remote attacker could possibly use this issue to bypass certain UPDATE and SELECT policies. This issue only affected Ubuntu 23.04.
 (CVE-2023-39418)

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.
