For anyone that is interested, I have found that the dm-crypt issue,
CVE-2004-2136, was addressed in the 2.6.10 kernel release. The
cryptoloop issue, CVE-2004-2135, still exists.

So, should cryptoloop be removed from the kernel? I've heard elsewhere
that it is already deprecated, so perhaps now is the time to finally get
rid of it.

Best wishes,
Mike
