DESCRIPTION
 Heartbeat[1] is a basic high availability system component for
 linux.
 
 Nathan Wallwork reported several format string vulnerabilities[2] in
 heartbeat that could possibly be used by a remote attacker to execute
 arbitrary code with root privileges.


SOLUTION
 It is recommended that all heartbeat users upgrade their packages.
 
 IMPORTANT: if the service is already running, it is necessary to
 manually restart it after the upgrade. To do so, please execute the
 following as root:
 
 service heartbeat restart
