|---|---|---|---|---|
| CVE-2017-18350 | 1 Bitcoin | 1 Bitcoin Core | 2024-08-05 | 5.9 Medium |
| 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. | ||||
| CVE-2017-12842 | 1 Bitcoin | 1 Bitcoin Core | 2024-08-05 | 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-2017-9230 | 1 Bitcoin | 1 Bitcoin | 2024-08-05 | 7.5 High |
| 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 | ||||
| CVE-2018-20587 | 2 Bitcoin, Bitcoinknots | 2 Bitcoin Core, Bitcoin Knots | 2024-08-05 | N/A |
| 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. | ||||
| CVE-2018-20586 | 1 Bitcoin | 1 Bitcoin Core | 2024-08-05 | 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-2018-17144 | 2 Bitcoin, Bitcoinknots | 2 Bitcoin Core, Bitcoin Knots | 2024-08-05 | 7.5 High |
| Bitcoin Core 0.14.x before 0.14.3, 0.15.x before 0.15.2, and 0.16.x before 0.16.3 and Bitcoin Knots 0.14.x through 0.16.x before 0.16.3 allow a remote denial of service (application crash) exploitable by miners via duplicate input. An attacker can make bitcoind or Bitcoin-Qt crash. | ||||
| CVE-2018-17145 | 7 Bcoin, Bitcoin, Bitcoinknots and 4 more | 7 Bcoin, Bitcoin Core, Bitcoin Knots and 4 more | 2024-08-05 | 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-2019-15947 | 1 Bitcoin | 1 Bitcoin Core | 2024-08-05 | 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-2020-14198 | 1 Bitcoin | 1 Bitcoin Core | 2024-08-04 | 7.5 High |
| Bitcoin Core 0.20.0 allows remote denial of service. | ||||
| CVE-2021-31876 | 1 Bitcoin | 1 Bitcoin | 2024-08-03 | 6.5 Medium |
| 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. | ||||
| CVE-2021-3195 | 1 Bitcoin | 1 Bitcoin Core | 2024-08-03 | 7.5 High |
| 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-2021-3401 | 1 Bitcoin | 1 Bitcoin | 2024-08-03 | 9.8 Critical |
| 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." | ||||
| CVE-2023-50428 | 2 Bitcoin, Bitcoinknots | 2 Bitcoin Core, Bitcoin Knots | 2024-08-02 | 5.3 Medium |
| In Bitcoin Core through 26.0 and Bitcoin Knots before 25.1.knots20231115, datacarrier size limits can be bypassed by obfuscating data as code (e.g., with OP_FALSE OP_IF), as exploited in the wild by Inscriptions in 2022 and 2023. NOTE: although this is a vulnerability from the perspective of the Bitcoin Knots project, some others consider it "not a bug." | ||||
| CVE-2023-33297 | 1 Bitcoin | 1 Bitcoin Core | 2024-08-02 | 7.5 High |
| Bitcoin Core before 24.1, when debug mode is not used, allows attackers to cause a denial of service (e.g., CPU consumption) because draining the inventory-to-send queue is inefficient, as exploited in the wild in May 2023. | ||||
