Debian: DSA-174-1 Critical: Heartbeat Buffer Overflow Remote Attack

Nathan Wallwork discovered a buffer overflow in heartbeat, a subsystem
for High-Availability Linux. A remote attacker could send a specially
crafted TCP 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.

sources.list as given below:

You may use an automated update by adding the resources from the
footer to the proper configuration.
