CVE-2023-50428 2 Bitcoin, Bitcoinknots 2 Bitcoin Core, Bitcoin Knots 2024-04-11 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 2024-04-11 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-2023-37192 1 Bitcoin 1 Bitcoin Core 2023-12-10 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-2023-33297 1 Bitcoin 1 Bitcoin Core 2023-12-10 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-2017-12842 1 Bitcoin 1 Bitcoin Core 2023-12-10 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 2023-12-10 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-2018-17145 7 Bcoin, Bitcoin, Bitcoinknots and 4 more 7 Bcoin, Bitcoin Core, Bitcoin Knots and 4 more 2023-12-10 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-2015-3641 1 Bitcoin 1 Bitcoin Core 2023-12-10 5.0 MEDIUM 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-2020-14198 1 Bitcoin 1 Bitcoin Core 2023-12-10 5.0 MEDIUM 7.5 HIGH
Bitcoin Core 0.20.0 allows remote denial of service.
CVE-2017-18350 1 Bitcoin 1 Bitcoin Core 2023-12-10 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-2019-15947 1 Bitcoin 1 Bitcoin Core 2023-12-10 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-2018-20587 2 Bitcoin, Bitcoinknots 2 Bitcoin Core, Bitcoin Knots 2023-12-10 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-2016-10724 1 Bitcoin 3 Bitcoin-qt, Bitcoin Core, Bitcoind 2023-12-10 7.8 HIGH 7.5 HIGH
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-2016-10725 1 Bitcoin 3 Bitcoin-qt, Bitcoin Core, Bitcoind 2023-12-10 5.0 MEDIUM 7.5 HIGH
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-2012-1909 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2023-12-10 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-2012-2459 1 Bitcoin 1 Bitcoin Core 2023-12-10 5.0 MEDIUM N/A
Unspecified vulnerability in bitcoind and Bitcoin-Qt before 0.4.6, 0.5.x before 0.5.5, 0.6.0.x before 0.6.0.7, and 0.6.x before 0.6.2 allows remote attackers to cause a denial of service (block-processing outage and incorrect block count) via unknown behavior on a Bitcoin network.
CVE-2011-4447 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2023-12-10 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.
CVE-2012-3789 1 Bitcoin 1 Bitcoin Core 2023-12-10 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-2012-4684 1 Bitcoin 4 Bitcoin-qt, Bitcoin Core, Bitcoind and 1 more 2023-12-10 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.
