    CVE-2021-44225

    Summary: keepalived security update

    Details: High Availability monitor built upon LVS, VRRP and service pollers. Security Fix(es): 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)
