wget ftp://ftp.sonic.net/mirrors/linux-kernels/v2.4/linux-2.4.25.tar.bz2

AFAIK, 2.4.25 is not vulnerable to this.  Or do you know something that
the advisory doesn't mention?  I ran the POC on my 2.4.25 boxes,
(removing the checks for version <=2.4.24) and I can't get root, d00d!

If you have a working exploit for 2.4.25, share it.  I want to root
bolt! ;)  (Hi, Scott ;-) )
