Initial attempt at a fix for CVE 2007 4965
I've uploaded this upstream too ... I'm not convinced it's everything that is
needed, so any security team review would be nice :)

Fix typo in initial patch
Of course, initial patch had a typo in it.
This should now be fixed, please test.
python-2.5-14.fc7 has been pushed to the Fedora 7 testing repository. If problems still persist, please make note of it in this bug report.
If you want to test the update, you can install it with
su -c 'yum --enablerepo=updates-testing update python'
python-2.5-14.fc7 has been pushed to the Fedora 7 stable repository. If problems still persist, please make note of it in this bug report.
James, please do an update for FC6 also, use 373281 for it. Thanks!
So given this applies to FC-6 and we want to fix that ... I assume we want to
fix RHEL-5 too? (very close to FC-6 python). I've put the patch in there too,
but I need a BZ with flags etc.
RHEL-4 looks vulnerable too, as does RHEL-3.
