| CVE-2020-14198 | 1 Bitcoin | 1 Bitcoin Core | 2022-12-06 | 5.0 MEDIUM | 7.5 HIGH |
| Bitcoin Core 0.20.0 allows remote denial of service. | |||||
| CVE-2019-15947 | 1 Bitcoin | 1 Bitcoin Core | 2022-05-03 | 5.0 MEDIUM | 7.5 HIGH |
| 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. | |||||
| CVE-2021-3195 | 1 Bitcoin | 1 Bitcoin Core | 2021-03-08 | 5.0 MEDIUM | 7.5 HIGH |
| ** DISPUTED ** bitcoind in Bitcoin Core through 0.21.0 can create a new file in an arbitrary directory (e.g., outside the ~/.bitcoin directory) via a dumpwallet RPC call. NOTE: this reportedly does not violate the security model of Bitcoin Core, but can violate the security model of a fork that has implemented dumpwallet restrictions. | |||||
| CVE-2018-17145 | 7 Bcoin, Bitcoin, Bitcoinknots and 4 more | 7 Bcoin, Bitcoin Core, Bitcoin Knots and 4 more | 2020-09-15 | 5.0 MEDIUM | 7.5 HIGH |
| Bitcoin Core 0.16.x before 0.16.2 and Bitcoin Knots 0.16.x before 0.16.2 allow remote denial of service via a flood of multiple transaction inv messages with random hashes, aka INVDoS. NOTE: this can also affect other cryptocurrencies, e.g., if they were forked from Bitcoin Core after 2017-11-15. | |||||
| CVE-2017-12842 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-23 | 5.0 MEDIUM | 7.5 HIGH |
| Bitcoin Core before 0.14 allows an attacker to create an ostensibly valid SPV proof for a payment to a victim who uses an SPV wallet, even if that payment did not actually occur. Completing the attack would cost more than a million dollars, and is relevant mainly only in situations where an autonomous system relies solely on an SPV proof for transactions of a greater dollar amount. | |||||
| CVE-2018-20586 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-20 | 4.3 MEDIUM | 5.3 MEDIUM |
| bitcoind and Bitcoin-Qt prior to 0.17.1 allow injection of arbitrary data into the debug log via an RPC call. | |||||
| CVE-2013-2293 | 1 Bitcoin | 3 Bitcoin-qt, Bitcoin Core, Bitcoind | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2012-3789 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2012-4682 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2012-4683 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2012-4684 | 1 Bitcoin | 4 Bitcoin-qt, Bitcoin Core, Bitcoind and 1 more | 2020-03-18 | 7.8 HIGH | N/A |
| 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. | |||||
| CVE-2013-2272 | 1 Bitcoin | 3 Bitcoin-qt, Bitcoin Core, Bitcoind | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2013-2273 | 1 Bitcoin | 3 Bitcoin-qt, Bitcoin Core, Bitcoind | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2013-2292 | 1 Bitcoin | 3 Bitcoin-qt, Bitcoin Core, Bitcoind | 2020-03-18 | 7.8 HIGH | N/A |
| 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. | |||||
| CVE-2013-3219 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2013-3220 | 1 Bitcoin | 4 Bitcoin-qt, Bitcoin Core, Bitcoind and 1 more | 2020-03-18 | 6.4 MEDIUM | N/A |
| 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. | |||||
| CVE-2013-4165 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-18 | 4.3 MEDIUM | N/A |
| 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. | |||||
| CVE-2013-4627 | 1 Bitcoin | 1 Bitcoin Core | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2012-1909 | 1 Bitcoin | 2 Bitcoin Core, Wxbitcoin | 2020-03-18 | 5.0 MEDIUM | N/A |
| 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. | |||||
| CVE-2011-4447 | 1 Bitcoin | 2 Bitcoin Core, Wxbitcoin | 2020-03-18 | 4.3 MEDIUM | N/A |
| 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. | |||||
