CVE-2011-4447 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2024-11-21 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-2010-5141 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2024-11-21 7.5 HIGH N/A
wxBitcoin and bitcoind before 0.3.5 do not properly handle script opcodes in Bitcoin transactions, which allows remote attackers to spend bitcoins owned by other users via unspecified vectors.
CVE-2010-5140 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2024-11-21 5.0 MEDIUM N/A
wxBitcoin and bitcoind before 0.3.13 do not properly handle bitcoins associated with Bitcoin transactions that have zero confirmations, which allows remote attackers to cause a denial of service (invalid-transaction flood) by sending low-valued transactions without transaction fees.
CVE-2010-5139 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2024-11-21 7.5 HIGH N/A
Integer overflow in wxBitcoin and bitcoind before 0.3.11 allows remote attackers to bypass intended economic restrictions and create many bitcoins via a crafted Bitcoin transaction.
CVE-2010-5138 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2024-11-21 5.0 MEDIUM N/A
wxBitcoin and bitcoind 0.3.x allow remote attackers to cause a denial of service (electricity consumption) via a Bitcoin transaction containing multiple OP_CHECKSIG script opcodes.
CVE-2010-5137 1 Bitcoin 2 Bitcoin Core, Wxbitcoin 2024-11-21 5.0 MEDIUM N/A
wxBitcoin and bitcoind before 0.3.5 allow remote attackers to cause a denial of service (daemon crash) via a Bitcoin transaction containing an OP_LSHIFT script opcode.
CVE-2021-3195 1 Bitcoin 1 Bitcoin Core 2024-08-03 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-2023-50428 2 Bitcoin, Bitcoinknots 2 Bitcoin Core, Bitcoin Knots 2024-08-02 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-2023-37192 1 Bitcoin 1 Bitcoin Core 2024-02-28 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 2024-02-28 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-2015-3641 1 Bitcoin 1 Bitcoin Core 2024-02-28 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-2017-18350 1 Bitcoin 1 Bitcoin Core 2024-02-28 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-2018-17145 7 Bcoin, Bitcoin, Bitcoinknots and 4 more 7 Bcoin, Bitcoin Core, Bitcoin Knots and 4 more 2024-02-28 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-2020-14198 1 Bitcoin 1 Bitcoin Core 2024-02-28 5.0 MEDIUM 7.5 HIGH
Bitcoin Core 0.20.0 allows remote denial of service.
CVE-2017-12842 1 Bitcoin 1 Bitcoin Core 2024-02-28 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 2024-02-28 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-2019-15947 1 Bitcoin 1 Bitcoin Core 2024-02-28 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.
