Debian DLA-3388-1 : keepalived - LTS security update

medium Nessus Plugin ID 174041

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3388 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 these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the keepalived packages.

For Debian 10 buster, this problem has been fixed in version 1
