Package        : traceroute-nanog
Vulnerability  : buffer overflow
Problem-Type   : local, remote
Debian-specific: no
CVE Id         : CAN-2002-1051 CAN-2002-1364 CAN-2002-1386 CAN-2002-1387
BugTraq Id     : 4956 6166 6274 6275

A vulnerability has been discovered in NANOG traceroute, an enhanced
version of the Van Jacobson/BSD traceroute program.  A buffer overflow
occurs in the 'get_origin()' function.  Due to insufficient bounds
checking performed by the whois parser, it may be possible to corrupt
memory on the system stack.  This vulnerability can be exploited by a
remote attacker to gain root privileges on a target host.  Though,
most probably not in Debian.

The Common Vulnerabilities and Exposures (CVE) project additionally
identified the following vulnerabilities which were already fixed in
the Debian version in stable (woody) and oldstable (potato) and are
mentioned here for completeness (and since other distributions had to
release a separate advisory for them):

 * CAN-2002-1364 (BugTraq ID 6166) talks about a buffer overflow in
   the get_origin function which allows attackers to execute arbitrary
   code via long WHOIS responses.

 * CAN-2002-1051 (BugTraq ID 4956) talks about a format string
   vulnerability that allows local users to execute arbitrary code via
   the -T (terminator) command line argument.

 * CAN-2002-1386 talks about a buffer overflow that may allow local
   users to execute arbitrary code via a long hostname argument.

 * CAN-2002-1387 talks about the spray mode that may allow local users   to overwrite arbitrary memory locations.

Fortunately, the Debian package drops privileges quite early after
startup, so those problems aer not likely to result in an exploit on a
Debian machine.

For the current stable distribution (woody) the above problem has been
fixed in version 6.1.1-1.2.
For the old stable distribution (potato) the above problem has been
fixed in version 6.0-2.2.

For the unstable distribution (sid) these problems have been fixed in
version 6.3.0-1.

We recommend that you upgrade your traceroute-nanog package.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

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