[tech] isec-ptrace-kmod-exploit

[Davyd]

This seems twisted and wrong.

I have a system patched against this exploit (2.4.21-rc7-ac1). However,
it only protects against versions of the exploit I compiled after I
started running a patched kernel.
Any version I compiled before I had a patched kernel still works on my
system, and still gives me root.
However, a version copied from another machine, compiled before the
patch, won't give me root (this implies that we should be safe).

Can anyone explain this?
