Use CVE-2014-3985 for the buffer overflow.
In the "investigated this and found it to be safe" sentence, "this"
means only the second part of the original message, not the part about
the buffer overflow. The while loop in the unpatched code before
3a87aa2f10bd7f1408e1849bdb59c41dd63a9fe9 was not found to be safe.
(For many people reading the second message, this may have been
obvious because the "safe" sentence came after quoted text from only
the second part of the original message.)
