Incident note: 74638 - value overflow (2010)

bad-txns-vout-toolarge is the 2010 overflow incident (CVE-2010-5139). A transaction created two outputs of about 92 billion BTC each. The outputs were non-negative, so they passed the then-current per-output check; their sum overflowed a signed 64-bit integer and wrapped negative, so the input-versus-output check passed too. Bitcoin 0.3.10 added a money-range check (there is no BIP). Core now rejects any single output above MAX_MONEY with this string.
