Description

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

Affected products

• Fedoraproject Fedora: 34, 35
• Keepalived: through 2.2.4
