Bitcoin Core vulnerabilities

Bitcoin Core prior to versions 29.5, 30.4, 31.2, and 32.1 is vulnerable to an out-of-memory (OOM) issue. The flaw can cause node malfunction due to insufficient memory resources.

Bitcoin Core through version 31.1 is vulnerable to a Denial of Service attack via undo files that have no size limit. The lack of size restriction may allow resource exhaustion and node destabilization.

Bitcoin Core prior to 29.5, 30.4, 31.2, and 32.1 is vulnerable to an OOM (out-of-memory) issue. The description does not provide further technical details.

Bitcoin Core through version 28.x has a security issue, the details of which are not disclosed. The earliest affected version is 0.14.

Memory management and protection issues in Bitcoin Core v22 allow attackers to modify the stored sending address within the app's memory, potentially enabling them to redirect Bitcoin transactions to wallets of their own choosing.

Bitcoin Core before version 24.1, when debug mode is not used, allows attackers to cause a denial of service (e.g., CPU consumption) due to inefficient draining of the inventory-to-send queue, as exploited in the wild in May 2023.
