[PATCH 0/1] Help wanted grafting Expat (CVE-2016-0718)

[Leo Famulari <leo@famulari.name>]

I've attached my attempt at fixing CVE-2016-0718 in Expat [0]. The
grafted expat updates to 2.1.1 and applies the patch from [1].

The problem is that, when trying build something that depends on expat,
I seem to have to rebuild *many* things.

Any advice?

By the way, there are some other caveats with this change.

First, I don't yet know the relationship of the patch from oss-sec to
upstream. It's not in their git repo. It might be a squashed
representation of the branch 'cve-2016-0718-fix-2-2-1' that they merged
yesterday [2]. I changed the line endings from DOS to Unix.

Second, I updated the grafted expat to 2.1.1 since the patch did not
apply to 2.1.0. I don't know if 2.1.1 is binary compatible with 2.1.0,
so I don't know if it's even suitable for grafting.
