This raises a very good question - why are known-insecure kernels
still being officially distributed? If you use stable you'll get a
2002 binary if you chose "kernel-image-2.4.18-686" but a secure kernel
if you chose "kernel-image-2.4.18-1-686" instead - quite a difference
from a seeming insignificant version number change. It's hard to think
of a scenario where it wouldn't be preferable to pull the bad packages
or at least include a prominent "Your system has a major security
hole" warning and a suggestion that you install the patched kernel
instead.
This has definitely improved in sarge where you have the
"kernel-image-2.4-686" and "kernel-image-2.6-686" packages with
dependencies tracking the current kernel, making the easy choice the
secure one as well.
