heartbeat - buffer overflow

Nathan Wallwork
discovered a buffer overflow in heartbeat, a subsystem
for High-Availability Linux. A remote attacker could send a specially
crafted UDP packet that overflows a buffer, leaving heartbeat to
execute arbitrary code as root.

This problem has been fixed in version 0.4.9.0l-7.2 for the current
stable distribution (woody) and version 0.4.9.2-1 for the unstable
distribution (sid). The old stable distribution (potato) doesn’t
contain a heartbeat package.

We recommend that you upgrade your heartbeat package immediately if
you run internet connected servers that are heartbeat-monitored.
