SATWEI summary

Beyond the crash already made public, CVE-2018-17144 let a miner inflate the Bitcoin supply in versions 0.15.X to 0.16.2 by spending an output twice inside one transaction. Developers held back that part to give systems time to move to 0.16.3 or 0.17.0rc4. Over half the hashrate is believed patched, no exploit attempts are known, and affected users are urged to upgrade.
