The remote operating system can be identified based on its UDP
The remote host appears to be run a version of the Linux kernel that
sends UDP responses in which the IP identification field is constant and
equal to zero (0).
With this information, an attacker could mount further, more targeted
attacks against this host.
Note that RedHat does not consider this a security issue as there are
many ways to identify or fingerprint a Linux host.
