Vulnerability Assessment Details
Detailed Explanation for this Vulnerability Assessment
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 rights 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):
Fortunately, the Debian package drops rights quite early after
startup, so those problems are not likely to result in an exploit on a
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
We recommend that you upgrade your traceroute-nanog package.
