Oracle Linux 9 : unbound (ELSA-2024-1750)

high Nessus Plugin ID 193173

Language:

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 9 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2024-1750 advisory.

 - A vulnerability was found in Unbound due to incorrect default permissions, allowing any process outside the unbound group to modify the unbound runtime configuration. If a process can connect over localhost to port 8953, it can alter the configuration of unbound.service. This flaw allows an unprivileged attacker to manipulate a running instance, potentially altering forwarders, allowing them to track all queries forwarded by the local resolver, and, in some cases, disrupting resolving altogether. (CVE-2024-1488)

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

Solution

Update the affected packages.
