high Nessus Plugin ID 182001

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of postgresql installed on the remote host is prior to 13.3-2. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2POSTGRESQL13-2023-003 advisory.

- A flaw was found in postgresql in versions before 13.3, before 12.7, before 11.12, before 10.17 and before 9.6.22. While modifying certain SQL array values, missing bounds checks let authenticated database users write arbitrary bytes to a wide area of server memory. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2021-32027)

- A flaw was found in postgresql. Using an INSERT ... ON CONFLICT ... DO UPDATE command on a purpose-crafted table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from this vulnerability is to data confidentiality. (CVE-2021-32028)

- A flaw was found in postgresql. Using an UPDATE ... RETURNING command on a purpose-crafted table, an authenticated database user could read arbitrary bytes of server memory. The highest threat from this vulnerability is to data confidentiality. (CVE-2021-32029)

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

Solution

Run 'yum update postgresql' to update your system.
