2.0.38 fixes a glitch

Freshmeat says:

Following up to yesterday's Linux 2.0.38 release, Alan Cox sent out a
security notice about a remote network DoS vulnerability which is
present in all Linux 2.0.x systems. Linux 2.2.x is not affected by
this bug. Causing this requires a great deal of skill and probably a
reasonably local network access as it is extremely timing
dependant. Nevertheless everyone is advised to upgrade systems with
kernels prior to 2.0.38 immediately.

[mod: More details will be published at a later time. The problem is
still hard to exploit, but with the added details, there is bound to
be someone who will try. -- REW]
