Comment 2 Petr Gajdos 2016-02-15 12:41:47 UTC 
I assume this bug is connected to 'Heap Overflow' of
http://blog.talosintel.com/2016/02/vulnerability-spotlight-libgraphite.html

There are two commits in the ubuntu bug, second reverting the first one. Please, either provide testcase or confirm that the second commit fixes the issue.

Thank you
Comment 3 Sebastian Krahmer 2016-02-15 13:29:23 UTC 
I think they need to be applied in order.

Second commit says its reworking previous fix. Presumably they
insufficiently fixed the issues with the first commit. Only parts
are reverted in the second commit; but also adding additional
checks.
