Amazon Linux 2 : libpq (ALASPOSTGRESQL14-2024-005)

high Nessus Plugin ID 189479

Language:

Synopsis

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

Description

The version of libpq installed on the remote host is prior to 14.10-1. It is, therefore, affected by a vulnerability as referenced in the ALAS2POSTGRESQL14-2024-005 advisory.

 - A flaw was found in PostgreSQL that allows authenticated database users to execute arbitrary code through missing overflow checks during SQL array value modification. This issue exists due to an integer overflow during array modification where a remote user can trigger the overflow by providing specially crafted data. This enables the execution of arbitrary code on the target system, allowing users to write arbitrary bytes to memory and extensively read the server's memory. (CVE-2023-5869)

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 libpq' to update your system.
