We do process external data. The advisory states "the vulnerability should
not be present in most Python builds out there, especially not the builds
for the Windows or Mac OS X platform provided by www.python.org."  except
for "... Python builds configured to support UCS-4 Unicode strings (using
the --enable-unicode=ucs4 configure flag). This is still not the default"

I guess I should have originally asked: Is the python build shipped with
FWTools 2.2.6 configured to support UCS-4 Unicode strings?

Well, if it is python 2.3.4 in FWTools then the security advisory seems
to indicate it is an issue.  But it should only have an impact if
externally supplied UCS-4 strings are passed through repr().  Do you
use Python scripts to process externally supplied data?
