Ubuntu 18.04 LTS / 20.04 LTS : Keepalived vulnerability (USN-5188-1)

medium Nessus Plugin ID 156042

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 21.04 / 21.10 host has a package installed that is affected by a vulnerability as referenced in the USN-5188-1 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

Update the affected keepalived package.
