The patches LGTM. I'm confused by CVE-2016-4658, the only "affected
products" seem to be Apple-based platforms, yet the code itself does
not seem platform-specific. And it looks like a serious vulnerability.

The other patch is less severe, but at least has some references in free
software circles. I'd say push them. Should it be grafted, or can we
wait for the next 'core-updates' evaluation?

I did not look into the other Debian patches.
