CVE-2018-19044

keepalived 2.0.8 didn’t check for pathnames with symlinks when writing data
to a temporary file upon a call to PrintData or PrintStats. This allowed
local users to overwrite arbitrary files if fs.protected_symlinks is set to
0, as demonstrated by a symlink from /tmp/keepalived.data or
/tmp/keepalived.stats to /etc/passwd.
