[SLUG] Security warning

[Ken Caldwell <kencaldwell@xxxxxxxxxxxxxxxx>]

Following Rebecca's talk last Friday I ran nessus over my computers.
Included in the reports generated was the following warning:

. Warning found on port general/tcp

The remote host uses non-random IP IDs, that is, it is
possible to predict the next value of the ip_id field of
the ip packets sent by this host.

An attacker may use this feature to determine if the remote
host sent a packet in reply to another request. This may be
used for portscanning and other things.

Solution : Contact your vendor for a patch

Risk factor :
 Low

It doesn't look serious but does such a patch exist for linux?
Just curious,
Ken
