You would have to analyse all of the security issues that have occurred
between the final release of 0.9.8 and the most up to date release of
1.0.2 (the oldest currently supported release). For each one you would
have to determine whether it is applicable to the 0.9.8 release and
then, if it is, backport it, which is likely to mean making a number of
changes to the patch. You're only going to be protected for that
security issue if you manage it without screwing up somewhere.
This is a *huge* amount of work. Do-able in theory. In practice - don't
