Debian DSA-330-1 : tcptraceroute - failure to drop root privileges

high Nessus Plugin ID 15167

Synopsis

The remote Debian host is missing a security-related update.

Description

tcptraceroute is a setuid-root program which drops root privileges after obtaining a file descriptor used for raw packet capture.
However, it did not fully relinquish all privileges, and in the event of an exploitable vulnerability, root privileges could be regained.

No current exploit is known, but this safeguard is being repaired in order to provide a measure of containment in the event that an exploitable flaw should be discovered.

Solution

For the stable distribution (woody) this problem has been fixed in version 1.2-2.

The old stable distribution (potato) does not contain a tcptraceroute package.

We recommend that you update your tcptraceroute package.
