| CVE-2024-52919 | Med | 0.42 | 6.5 | 0.00 | Nov 18, 2024 | Bitcoin Core before 22.0 has a CAddrMan nIdCount integer overflow and resultant assertion failure (and daemon exit) via a flood of addr messages. | ||
| CVE-2024-52918 | Med | 0.42 | 6.5 | 0.00 | Nov 18, 2024 | Bitcoin-Qt in Bitcoin Core before 0.20.0 allows remote attackers to cause a denial of service (memory consumption and application crash) via a BIP21 r parameter for a URL that has a large file. | ||
| CVE-2024-52917 | Med | 0.42 | 6.5 | 0.00 | Nov 18, 2024 | Bitcoin Core before 22.0 has a miniupnp infinite loop in which it allocates memory on the basis of random data received over the network, e.g., large M-SEARCH replies from a fake UPnP device. | ||
| CVE-2021-31876 | Med | 0.42 | 6.5 | 0.02 | May 13, 2021 | Bitcoin Core 0.12.0 through 0.21.1 does not properly implement the replacement policy specified in BIP125, which makes it easier for attackers to trigger a loss of funds, or a denial of service attack against downstream projects such as Lightning network nodes. An unconfirmed… | ||
| CVE-2016-10725 | Hig | 0.42 | 7.5 | 0.02 | Jul 5, 2018 | 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… | ||
| CVE-2016-10724 | Hig | 0.42 | 7.5 | 0.02 | Jul 5, 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… | ||
| CVE-2017-18350 | Med | 0.38 | 5.9 | 0.01 | Mar 12, 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.

FillBlock can be called twice for one… | ||
| CVE-2023-33297 | Hig | 0.00 | 7.5 | 0.01 | May 22, 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. | ||
| CVE-2013-5700 | 0.00 | — | 0.02 | Sep 10, 2013 | 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. | |||
