09 Dec 2023 — 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."

22 May 2023 — 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. A vulnerability has been discovered in Bitcoin, which can lead to a denial of service. Versions greater than or equal to 25.0 are affected. • https://en.bitcoin.it/wiki/Common_Vulnerabilities_and_Exposures • CWE-400: Uncontrolled Resource Consumption •

21 Jan 2021 — 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 ** EN DISPUTA ** bitcoind en Bitcoin Core versiones hasta 0.21.0, puede crear un nuevo archivo en un directorio arbitrario (por ejemplo, fuera del directorio ~/.bitcoin) por medio de una llam... • https://github.com/bitcoin/bitcoin/issues/20866 • CWE-20: Improper Input Validation •

16 Mar 2020 — 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.

12 Mar 2020 — 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. bitcoind y Bitcoin-Qt versiones anteriores a 0.15.1, presentan un desbordamiento de búfer en la región stack de la memoria si es usado un servidor proxy SOCKS controlado por el atacante.

05 Jul 2018 — 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.
