Subject: Re: [FD] Freeware Advanced Audio Decoder 2 (FAAD2) multiple
	vulnerabilities

Nice finds!

Just a comment about "memory allocation errors". These would not
typically be considered a "vulnerability", unless there's something
obviously wrong with how much memory is allocated and possibly later
used. Allocation errors are in vast majority of cases reported to
end-users of tool/service, and it's considered a correct way of
handling this kind of problems.

Maybe faad could have a config option, like libjpeg what provides,
which limits size of single and total mem allocations, but it seems
optional.
