Avail. 1 CVE-2019-159473262019-09-052019-09-09NoneRemoteLowNot requiredPartialNoneNone In Bitcoin Core 0.18.0, bitcoin-qt stores wallet.dat data unencrypted in memory. Upon a crash, it may dump a core file. If a user were to mishandle a core file, an attacker can reconstruct the user's wallet.dat file, including their private keys, via a grep "6231 0500" command. 2 CVE-2018-205872019-02-112019-10-02NoneLocalLowNot requiredNonePartialNone Bitcoin Core 0.12.0 through 0.17.1 and Bitcoin Knots 0.12.0 through 0.17.x before 0.17.1.knots20181229 have Incorrect Access Control. Local users can exploit this to steal currency by binding the RPC IPv4 localhost port, and forwarding requests to the IPv6 localhost port. 3 CVE-2017-92303382017-05-242018-06-13NoneRemoteLowNot requiredPartialNoneNone ** DISPUTED ** The Bitcoin Proof-of-Work algorithm does not consider a certain attack methodology related to 80-byte block headers with a variety of initial 64-byte chunks followed by the same 16-byte chunk, multiple candidate root values ending with the same 4 bytes, and calculations involving sqrt numbers. This violates the security assumptions of (1) the choice of input, outside of the dedicated nonce area, fed into the Proof-of-Work function should not change its difficulty to evaluate and (2) every Proof-of-Work function execution should be independent. NOTE: a number of persons feel that this methodology is a benign mining optimization, not a vulnerability. 4 CVE-2016-107253102018-07-052019-07-17NoneRemoteLowNot requiredNoneNonePartial In Bitcoin Core before v0.13.0, a non-final alert is able to block the special "final alert" (which is supposed to override all other alerts) because operations occur in the wrong order. This behavior occurs in the remote network alert system (deprecated since Q1 2016). This affects other uses of the codebase, such as Bitcoin Knots before v0.13.0.knots20160814 and many altcoins. 5 CVE-2016-10724400 DoS 2018-07-052019-07-17NoneRemoteLowNot requiredNoneNoneComplete Bitcoin Core before v0.13.0 allows denial of service (memory exhaustion) triggered by the remote network alert system (deprecated since Q1 2016) if an attacker can sign a message with a certain private key that had been known by unintended actors, because of an infinitely sized map. This affects other uses of the codebase, such as Bitcoin Knots before v0.13.0.knots20160814 and many altcoins. 6 CVE-2013-5700189 DoS 2013-09-102013-09-13NoneRemoteLowNot requiredNoneNonePartial The Bloom Filter implementation in bitcoind and Bitcoin-Qt 0.8.x before 0.8.4rc1 allows remote attackers to cause a denial of service (divide-by-zero error and daemon crash) via a crafted sequence of messages. 7 CVE-2013-4627 DoS 2013-08-022013-10-11NoneRemoteLowNot requiredNoneNonePartial Unspecified vulnerability in bitcoind and Bitcoin-Qt 0.8.x allows remote attackers to cause a denial of service (memory consumption) via a large amount of tx message data. 8 CVE-2013-4165200 +Info 2013-08-022013-10-11NoneRemoteMediumNot requiredPartialNoneNone The HTTPAuthorized function in bitcoinrpc.cpp in bitcoind 0.8.1 provides information about authentication failure upon detecting the first incorrect byte of a password, which makes it easier for remote attackers to determine passwords via a timing side-channel attack. 9 CVE-2013-3220399 DoS 2013-08-022013-10-11NoneRemoteLowNot requiredNonePartialPartial bitcoind and Bitcoin-Qt before 0.4.9rc2, 0.5.x before 0.5.8rc2, 0.6.x before 0.6.5rc2, and 0.7.x before 0.7.3rc2, and wxBitcoin, do not properly consider whether a block's size could require an excessive number of database locks, which allows remote attackers to cause a denial of service (split) and enable certain double-spending capabilities via a large block that triggers incorrect Berkeley DB locking. 10 CVE-2013-3219264 Bypass 2013-08-022013-10-11NoneRemoteLowNot requiredNonePartialNone bitcoind and Bitcoin-Qt 0.8.x before 0.8.1 do not enforce a certain block protocol rule, which allows remote attackers to bypass intended access restrictions and conduct double-spending attacks via a large block that triggers incorrect Berkeley DB locking in older product versions. 11 CVE-2013-2293399 DoS 2013-03-122013-03-18NoneRemoteLowNot requiredNoneNonePartial The CTransaction::FetchInputs method in bitcoind and Bitcoin-Qt before 0.8.0rc1 copies transactions from disk to memory without incrementally checking for spent prevouts, which allows remote attackers to cause a denial of service (disk I/O consumption) via a Bitcoin transaction with many inputs corresponding to many different parts of the stored block chain. 12 CVE-2013-2292399 DoS 2013-03-122013-03-18NoneRemoteLowNot requiredNoneNoneComplete bitcoind and Bitcoin-Qt 0.8.0 and earlier allow remote attackers to cause a denial of service (electricity consumption) by mining a block to create a nonstandard Bitcoin transaction containing multiple OP_CHECKSIG script opcodes. 13 CVE-2013-2273200 +Info 2013-03-122013-03-18NoneRemoteLowNot requiredPartialNoneNone bitcoind and Bitcoin-Qt before 0.4.9rc1, 0.5.x before 0.5.8rc1, 0.6.0 before 0.6.0.11rc1, 0.6.1 through 0.6.5 before 0.6.5rc1, and 0.7.x before 0.7.3rc1 make it easier for remote attackers to obtain potentially sensitive information about returned change by leveraging certain predictability in the outputs of a Bitcoin transaction. 14 CVE-2013-2272200 +Info 2013-03-122013-03-18NoneRemoteLowNot requiredPartialNoneNone The penny-flooding protection mechanism in the CTxMemPool::accept method in bitcoind and Bitcoin-Qt before 0.4.9rc1, 0.5.x before 0.5.8rc1, 0.6.0 before 0.6.0.11rc1, 0.6.1 through 0.6.5 before 0.6.5rc1, and 0.7.x before 0.7.3rc1 allows remote attackers to determine associations between wallet addresses and IP addresses via a series of large Bitcoin transactions with insufficient fees. 15 CVE-2012-4684399 DoS 2013-03-122013-03-18NoneRemoteLowNot requiredNoneNoneComplete The alert functionality in bitcoind and Bitcoin-Qt before 0.7.0 supports different character representations of the same signature data, but relies on a hash of this signature, which allows remote attackers to cause a denial of service (resource consumption) via a valid modified signature for a circulating alert. 16 CVE-2012-4683 DoS 2012-09-142012-09-17NoneRemoteLowNot requiredNoneNonePartial Unspecified vulnerability in bitcoind and Bitcoin-Qt allows attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2012-4682. 17 CVE-2012-4682 DoS 2012-09-142012-09-17NoneRemoteLowNot requiredNoneNonePartial Unspecified vulnerability in bitcoind and Bitcoin-Qt allows attackers to cause a denial of service via unknown vectors, a different vulnerability than CVE-2012-4683. 18 CVE-2012-3789 DoS 2012-08-062012-08-07NoneRemoteLowNot requiredNoneNonePartial Unspecified vulnerability in bitcoind and Bitcoin-Qt before 0.4.7rc3, 0.5.x before 0.5.6rc3, 0.6.0.x before 0.6.0.9rc1, and 0.6.x before 0.6.3rc1 allows remote attackers to cause a denial of service (process hang) via unknown behavior on a Bitcoin network. 19 CVE-2012-2459 DoS 2012-08-062012-08-07NoneRemoteLowNot requiredNoneNonePartial Unspecified vulnerability in bitcoind and Bitcoin-Qt before 0.4.6, 0.5.x before 0.5.5, 0.6.0.x before 0.6.0.7, and 0.6.x before 0.6.2 allows remote attackers to cause a denial of service (block-processing outage and incorrect block count) via unknown behavior on a Bitcoin network. 20 CVE-2012-1910 DoS Exec Code 2012-08-062012-08-07NoneRemoteLowNot requiredPartialPartialPartial 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. 21 CVE-2012-190916 DoS 2012-08-062012-08-07NoneRemoteLowNot requiredNoneNonePartial 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. 22 CVE-2011-4447310 Bypass 2012-08-062012-08-07NoneRemoteMediumNot requiredPartialNoneNone 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. 23 CVE-2010-51412642012-08-062012-08-07NoneRemoteLowNot requiredPartialPartialPartial 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. 24 CVE-2010-5140119 DoS Overflow 2012-08-062012-08-07NoneRemoteLowNot requiredNoneNonePartial 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. 25 CVE-2010-5139189 Overflow Bypass 2012-08-062012-08-07NoneRemoteLowNot requiredPartialPartialPartial Integer overflow in wxBitcoin and bitcoind before 0.3.11 allows remote attackers to bypass intended economic restrictions and create many bitcoins via a crafted Bitcoin transaction. 26 CVE-2010-5138 DoS 2012-08-062012-08-07NoneRemoteLowNot requiredNoneNonePartial wxBitcoin and bitcoind 0.3.x allow remote attackers to cause a denial of service (electricity consumption) via a Bitcoin transaction containing multiple OP_CHECKSIG script opcodes. 27 CVE-2010-5137 DoS 2012-08-062012-08-07NoneRemoteLowNot requiredNoneNonePartial wxBitcoin and bitcoind before 0.3.5 allow remote attackers to cause a denial of service (daemon crash) via a Bitcoin transaction containing an OP_LSHIFT script opcode.
