Perhaps not very.  As I indicated in an earlier post, the exploit has been
available since 2001, so it is probably fairly hard to exploit.

If it's running 2.4.4 or 2.5 it should be okay.  If it's running some
earlier version a lot will depend on whether Python was installed by a Linux
distributor (in which case check their version numbers and their release
notes) or installed locally from source.

I can't pretend to divine the true meaning behind all the wording of the
various security advisories.  You'd have to ask each one of the security
organizations.

Here's one example:

    http://secunia.com/advisories/22276/

The application has to work with Unicode on a UCS-4-compiled version of
Python and use the repr() function on such Unicode strings.  Furthermore,
the black hat would have to figure out how to get a suitably crafted Unicode
string into the repr() function at just the right place.

I'm not saying it can't be done, but I think it would be a fairly
challenging undertaking.
