CVE-2023-50428 2 Bitcoin, Bitcoinknots 2 Bitcoin Core, Bitcoin Knots 2024-05-17 N/A 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-2021-3195 1 Bitcoin 1 Bitcoin Core 2024-05-17 5.0 MEDIUM 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-2018-17144 2 Bitcoin, Bitcoinknots 2 Bitcoin Core, Bitcoin Knots 2024-03-13 5.0 MEDIUM 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-2023-33297 1 Bitcoin 1 Bitcoin Core 2023-11-07 N/A 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-2018-20587 2 Bitcoin, Bitcoinknots 2 Bitcoin Core, Bitcoin Knots 2023-11-07 2.1 LOW 5.5 MEDIUM
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-2017-18350 1 Bitcoin 1 Bitcoin Core 2023-11-07 4.3 MEDIUM 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-2023-37192 1 Bitcoin 1 Bitcoin Core 2023-07-17 N/A 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-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-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-2013-4165 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-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-2013-2292 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-2013-3220 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-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-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-2012-4682 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.
