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.
