1 CVE-2021-31876 863 DoS 2021-05-13 2021-05-26
6.4
 None Remote Low Not required None Partial Partial
Bitcoin Core 0.12.0 through 0.21.1 does not properly implement the replacement policy specified in BIP125, which makes it easier for attackers to trigger a loss of funds, or a denial of service attack against downstream projects such as Lightning network nodes. An unconfirmed child transaction with nSequence = 0xff_ff_ff_ff, spending an unconfirmed parent with nSequence <= 0xff_ff_ff_fd, should be replaceable because there is inherited signaling by the child transaction. However, the actual PreChecks implementation does not enforce this. Instead, mempool rejects the replacement attempt of the unconfirmed child transaction.
2 CVE-2021-3401 77 Exec Code 2021-02-04 2021-02-08
7.5
 None Remote Low Not required Partial Partial Partial
Bitcoin Core before 0.19.0 might allow remote attackers to execute arbitrary code when another application unsafely passes the -platformpluginpath argument to the bitcoin-qt program, as demonstrated by an x-scheme-handler/bitcoin handler for a .desktop file or a web browser. NOTE: the discoverer states "I believe that this vulnerability cannot actually be exploited."
3 CVE-2021-3195 20 2021-01-26 2021-03-08
5.0
 None Remote Low Not required None Partial None
** 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.
4 CVE-2020-14198 DoS 2020-09-10 2022-12-06
5.0
 None Remote Low Not required None None Partial
Bitcoin Core 0.20.0 allows remote denial of service.
5 CVE-2019-15947 312 2019-09-05 2022-05-03
5.0
 None Remote Low Not required Partial None None
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.
6 CVE-2018-20587 2019-02-11 2019-10-03
2.1
 None Local Low Not required None Partial None
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.
7 CVE-2018-20586 116 2020-03-12 2020-03-20
4.3
 None Remote Medium Not required None Partial None
bitcoind and Bitcoin-Qt prior to 0.17.1 allow injection of arbitrary data into the debug log via an RPC call.
8 CVE-2018-17145 400 DoS 2020-09-10 2020-09-15
5.0
 None Remote Low Not required None None Partial
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.
9 CVE-2017-18350 120 Overflow 2020-03-12 2020-03-18
4.3
 None Remote Medium Not required None None Partial
bitcoind and Bitcoin-Qt prior to 0.15.1 have a stack-based buffer overflow if an attacker-controlled SOCKS proxy server is used. This results from an integer signedness error when the proxy server responds with an acknowledgement of an unexpected target domain name.
10 CVE-2017-12842 20 2020-03-16 2020-03-23
5.0
 None Remote Low Not required None Partial None
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.
11 CVE-2017-9230 338 2017-05-24 2018-06-14
5.0
 None Remote Low Not required Partial None None
** 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.
12 CVE-2016-10725 310 2018-07-05 2020-03-18
5.0
 None Remote Low Not required None None Partial
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.
13 CVE-2016-10724 400 DoS 2018-07-05 2020-03-18
7.8
 None Remote Low Not required None None Complete
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.
14 CVE-2015-3641 DoS 2020-03-12 2020-03-18

17 CVE-2013-4165 200 +Info 2013-08-02 2020-03-18
4.3
 None Remote Medium Not required Partial None None
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.
18 CVE-2013-3220 399 DoS 2013-08-02 2020-03-18
6.4
 None Remote Low Not required None Partial Partial
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.
19 CVE-2013-3219 264 Bypass 2013-08-02 2020-03-18
5.0
 None Remote Low Not required None Partial None
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.
20 CVE-2013-2293 399 DoS 2013-03-12 2020-03-18
5.0
 None Remote Low Not required None None Partial
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.
21 CVE-2013-2292 399 DoS 2013-03-12 2020-03-18
7.8
 None Remote Low Not required None None Complete
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.
22 CVE-2013-2273 200 +Info 2013-03-12 2020-03-18
