"Updated ircd-hybrid packages fix security vulnerability :

Bob Nomnomnom reported a Denial of Service vulnerability in
IRCD-Hybrid, an Internet Relay Chat server. A remote attacker may use
an error in the masks validation and crash the server (CVE-2013-0238).

Please note that due to the previously suboptimal nature of the
sysvinit script, systemd systems would not correctly detect the daemon
process as running and thus could not stop the service. As a result,
you may have to manually kill the process and start the service after
upgrading (i.e. killall ircd-hybrid; systemctl start
ircd-hybrid.service)."
