Bitcoin: Security Vulnerabilities
The Bitcoin protocol, as used in bitcoind before 0.4.4, wxBitcoin, Bitcoin-Qt, and other programs, does not properly handle multiple transactions with the same identifier, which allows remote attackers to cause a denial of service (unspendable transaction) by leveraging the ability to create a duplicate coinbase transaction.

Bitcoin-Qt 0.5.0.x before 0.5.0.5; 0.5.1.x, 0.5.2.x, and 0.5.3.x before 0.5.3.1; and 0.6.x before 0.6.0rc4 on Windows does not use MinGW multithread-safe exception handling, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted Bitcoin protocol messages.
