Unstable kernels !!!
I read today in a PC magazine that some Polish security group found a big security hole in the Linux kernels till the version 2.6 It has something to do with the component mremap which manages virtual memory. The security group states that the hole coud be used for remote execution of any program. It also says that there is a patch on RedHat's site for their systems. Maybe this should deserve some attention

It's true that the hole exists, but it can't be used for remote arbitrary code execution from any program. It can only used to raise your privileges once you have code running. It's fixed in 2.6.1 and 2.4.24.

Thanks kriss,
that book helped a lot. Although, I still have a lot to read. 
Would never have visited the official site.
