Comment 1 Sam Fowler 2018-11-21 05:34:15 UTC
Created keepalived tracking bugs for this issue:

Affects: fedora-all [bug 1651868]

Comment 4 Adam Mariš 2018-11-29 14:22:52 UTC
Statement:

This issue did not affect the versions of keepalived as shipped with Red Hat Enterprise Linux 6 and 7 as the packages are not built with dbus support, therefore the vulnerable code is not available in resulting RPM and the issue cannot be exploited.
