Bitcoin Core on Oct. 28 disclosed three security vulnerabilities identified by AI, with one allowing attackers to remotely crash Windows and Mac systems. The flaws, including two medium-severity memory-exhaustion issues and a low-severity file-overflow flaw, expose weaknesses in software used to validate transactions. Developers have released fixes in versions 29.5, 30.4, 31.2, and 32.1. Version 29.x has reached end-of-life, meaning no future security updates.
