|---|---|---|---|---|
| CVE-2023-50428 | 2 Bitcoin, Bitcoinknots | 2 Bitcoin Core, Bitcoin Knots | 2024-11-21 | 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-2023-37192 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 7.5 High |
| Memory management and protection issues in Bitcoin Core v22 allows attackers to modify the stored sending address within the app's memory, potentially allowing them to redirect Bitcoin transactions to wallets of their own choosing. | ||||
| CVE-2023-33297 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 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. | ||||
| CVE-2021-3195 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 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-2020-14198 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 7.5 High |
| Bitcoin Core 0.20.0 allows remote denial of service. | ||||
| CVE-2019-15947 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 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-2018-20587 | 2 Bitcoin, Bitcoinknots | 2 Bitcoin Core, Bitcoin Knots | 2024-11-21 | 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 | 2024-11-21 | 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-2018-17145 | 7 Bcoin, Bitcoin, Bitcoinknots and 4 more | 7 Bcoin, Bitcoin Core, Bitcoin Knots and 4 more | 2024-11-21 | 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-2018-17144 | 2 Bitcoin, Bitcoinknots | 2 Bitcoin Core, Bitcoin Knots | 2024-11-21 | 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-2017-18350 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 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 | 2024-11-21 | 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-2016-10725 | 1 Bitcoin | 3 Bitcoin-qt, Bitcoin Core, Bitcoind | 2024-11-21 | N/A |
| 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. | ||||
| CVE-2016-10724 | 1 Bitcoin | 3 Bitcoin-qt, Bitcoin Core, Bitcoind | 2024-11-21 | N/A |
| 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. | ||||
| CVE-2015-3641 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 7.5 High |
| bitcoind and Bitcoin-Qt prior to 0.10.2 allow attackers to cause a denial of service (disabled functionality such as a client application crash) via an "Easy" attack. | ||||
| CVE-2013-5700 | 1 Bitcoin | 2 Bitcoin-qt, Bitcoin Core | 2024-11-21 | N/A |
| 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. | ||||
| CVE-2013-4627 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 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-2013-4165 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 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-2013-3220 | 1 Bitcoin | 4 Bitcoin-qt, Bitcoin Core, Bitcoind and 1 more | 2024-11-21 | 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-2013-3219 | 1 Bitcoin | 1 Bitcoin Core | 2024-11-21 | 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. | ||||
