Description zurk 1999-10-04 23:30:13 UTC
Thought this would have been fixed by now..oh well...Here
goes (hope the formatting doesnt kill it) :
A weakness within the TCP stack in Linux 2.2.x kernels has
                discovered. The vulnerability makes it
possible to "blind-spoof" TCP
                It`s therefore possible for an attacker to
initiate a TCP connection
                from an arbitrary non existing or
unresponding IP source address,
                exploiting IP address based access control

                Linux 2.0.x kernels were tested against this
attack and found not to
                be vulnerable in any case.

The vulnerability :
The patches (1st fixes typo, 2nd fixes vulnerability):

Check 6.1 for it too...Also can we now have doom in X Games
? Dooms source is now GPLed.

Comment 1 Bill Nottingham 1999-10-05 14:20:59 UTC
This is fixed in the latest kernels in 6.1/Raw Hide.

As for Doom, while the source is available, IIRC, Id specfically
said that commercial redistribution was prohibited.
