I think it is great that Kyle is communicating the issues and helping
fixing issues. I did not intend to give "the stick" with my statement I
was referring to the situation back then, where I myself could have
probably handled the situation much better.
I too do not know very much about network security and how best to
report issues, though I can possibly help out contacting the
distribution security teams if needed.
The shared certificate is probably not a huge problem as the number of
AltNames for the mathjax certificate is quite small, but some googling
showed that this is indeed an attack vector:
But I don't know if this is relevant enough to require any more actions
