Regarding the apparent inconsistency: the incorrect patch was not just
used by Debian, but also by other distributions.  The upstream fix was
correct, though, so some backported patches for CVE-2006-5051 are not
affected by CVE-2008-4109, hence the two CVE names.

The missing mipsel packages will be delivered as soon as they are
available.
