Amazon Linux 2 : postgresql (ALAS-2024-2567)

high Nessus Plugin ID 200388

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 9.2.24-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2024-2567 advisory.

 While modifying certain SQL array values, missing overflow checks let authenticated database users write arbitrary bytes to a memory area that facilitates arbitrary code execution. Missing overflow checks also let authenticated database users read a wide area of server memory. The CVE-2021-32027 fix covered some attacks of this description, but it missed others. (CVE-2023-5869)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update postgresql' to update your system.
