traceroute bug fix update

An updated traceroute package that fixes two bugs is now available.

The traceroute utility displays the route used by IP packets on their way
to a specified network (or Internet) host. Traceroute displays the IP
address and hostname (if possible) of the machines along the route taken by
the packets.

This updated package fixes the following two bugs:

* routers using Multiprotocol Label Switching (MPLS) send certain MPLS data
in ICMP packets. The traceroute utility incorrectly rendered this MPLS
data, resulting in output such as "Icmp checksum is wrong". In this updated
package, traceroute renders MPLS data in accordance with RFC 4950 (ICMP
Extensions for Multiprotocol Label Switching), resulting in the correct
output for MPLS data, as well as making traceroute RFC 4950 compliant.

* the traceroute command "traceroute -F <host_name>" failed and the "packet
reassembles failed" counter incremented with each failure. (The latter
could be seen by issuing the "netstat -s" command). With this update,
"traceroute -F <host_name>" works as expected.

Users of traceroute are advised to upgrade to this updated package, which
resolves this issue.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
