CVE-2018-19044: Keepalived

Medium severity, CVSS 4.7. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
