Thanks for your analysis, we always appreciate this type of report.

I took an initial look at all of the issues reported and agree with
the assessments.

The one note is that I think (5) mxit_add_buddy NULL pointer deref.
isn't actually a security problem as such since it can only be
triggered by the user directly.

We will get CVEs for the rest of these items and address them
(hopefully in the next 2.10.8 release (no date set yet)).
We will credit "Fabian Yamaguchi and Christian Wressnegger of the
University of Goettingen" with finding these - does that sound


Thanks again,
