Dear Bitcore BTX community, exchanges, merchant processor, etc. Bitcore Core Wallet version 0.15.2.0 has now been released which includes a very important security fix for a DoS vulnerability, CVE-2018-17144!
Since Bitcore core is a hybrid fork of bitcoin core, it is liable to the same bug. All Bitcore core versions equivalent to bitcoin core 0.14.0 and above need to upgrade in order to be immune to this vulnerability.
As this update includes the fix for CVE-2018–17144, we would highly recommend all users upgrade as soon as possible.
What is this “transaction bug”
Security issue CVE-201-17144 (1) was discovered that older versions of Bitcoin Core will crash if they try to process a block containing a transaction that attempts to spend the same input twice. Such blocks are invalid, so they can only be created by
a miner willing to sacrifice their allowed income for creating a block of at least 12.5 BTC (about $80,000 USD as of this writing) (2).
