Publication date: 19 Dec 2021
URL: https://advisories.mageia.org/MGASA-2021-0567.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2021-44225

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).
