What is CVE-2012-1909?
The Bitcoin protocol, as implemented in various versions of bitcoind prior to 0.4.4, wxBitcoin, and Bitcoin-Qt, is susceptible to a vulnerability where the system fails to manage multiple transactions with the same identifier effectively. This deficiency allows remote attackers to exploit the situation by creating duplicate coinbase transactions, leading to unspendable transactions and ultimately causing a denial of service. For those relying on these versions, the implications can result in significant operational disruptions.
