2012-08-06 CVE-2012-1910 Unspecified vulnerability in Bitcoin Bitcoin-Qt and Bitcoin Core
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.

2012-08-06 CVE-2012-1909 Configuration vulnerability in Bitcoin Core and Wxbitcoin
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.

2012-08-06 CVE-2011-4447 Cryptographic Issues vulnerability in Bitcoin Core and Wxbitcoin
The "encrypt wallet" feature in wxBitcoin and bitcoind 0.4.x before 0.4.1, and 0.5.0rc, does not properly interact with the deletion functionality of BSDDB, which allows context-dependent attackers to obtain unencrypted private keys from Bitcoin wallet files by bypassing the BSDDB interface and reading entries that are marked for deletion.

2012-08-06 CVE-2010-5141 Permissions, Privileges, and Access Controls vulnerability in Bitcoin Core and Wxbitcoin
wxBitcoin and bitcoind before 0.3.5 do not properly handle script opcodes in Bitcoin transactions, which allows remote attackers to spend bitcoins owned by other users via unspecified vectors.

2012-08-06 CVE-2010-5140 Buffer Errors vulnerability in Bitcoin Core and Wxbitcoin
wxBitcoin and bitcoind before 0.3.13 do not properly handle bitcoins associated with Bitcoin transactions that have zero confirmations, which allows remote attackers to cause a denial of service (invalid-transaction flood) by sending low-valued transactions without transaction fees.
