[plug] do_brk() vuln with kernels < 2.4.23

[Chris Caston]

Hello,

I'm building a new firewall at the moment and currently my kernel is:

2.4.18-5woody5

Is this likely susceptible to do_brk() ?

I'm looking at upgrading to 2.6 stable but I've only ever done this
using Sid. 

Now I am hesitant to upgrade the firewall to sid as there has been no
updates since the Debian break-in. So I worry that at the same time
there they have been missing important security updates.

So what is the best path?

thanks,

Chris
