first of all, it has never been my intention to insult anyone. If that
is how it was received, I'm sorry.
Second: I sent in confirmed and _potential_ vulnerabilities and my hope
was that those developers who know the code base would make an informed
decision about whether or not to apply fixes or not.
I was then asked by Rafaël if I would work on patches so I made patches
for both the confirmed and potential vulnerabilities in order to help
out. Potential vulnerabilities have been clearly marked in the commit
messages. In cases where I was unsure, I also included conservative
checks to be on the save side, e.g., the SIZE_MAX checks you mentioned.
As I have said before, feel free to modify or discard any of these
patches. I am perfectly aware of the fact that you know the code base in
more detail than I do, which is why I sent in my report instead of
supplying patches straight away. I am sorry that I cannot invest the
time to build triggers for all of the potential bugs as well, however, I
would suggest rather going for more checks than less since they don't
hurt and it's often hard to say whether a variable will ever contain a
value or not.
To be honest, I was hoping for a slightly more friendly response for
responsibly disclosing at least two critical vulnerabilities to you: the
overflow in the MP4 demuxer and in the updater, and even writing patches
for you. If this was not the right thing to do, let me know.
