Amazon Linux 2 : keepalived (ALAS-2023-2168)

medium Nessus Plugin ID 178836

Language:

Synopsis

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

Description

The version of keepalived installed on the remote host is prior to 1.3.5-16. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2168 advisory.

- In Keepalived through 2.2.4, the D-Bus policy does not sufficiently restrict the message destination, allowing any user to inspect and manipulate any property. This leads to access-control bypass in some situations in which an unrelated D-Bus system service has a settable (writable) property (CVE-2021-44225)

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 keepalived' to update your system.
