Denial-of-Service vulnerability CVE-2018-17144
A denial-of-service vulnerability exploitable by miners has been discovered in Bitcoin Core versions 0.14.0 up to 0.16.2. It is recommended to upgrade any of the vulnerable versions to 0.14.3, 0.15.2 or 0.16.3 as soon as possible.
Since 0.14.0 the approximate transaction fee shown in Bitcoin-Qt when using coin control and smart fee estimation does not reflect any change in target from the smart fee slider. It will only present an approximate fee calculated using the default target. The fee calculated using the correct target is still applied to the transaction and shown in the final send confirmation dialog.
