Bitcoin Core Discloses Three Crash-Class Bugs — and Patches Every Maintained Version at Once
Bitcoin Core published three security advisories on 28 October: two unbounded-memory-growth flaws — one triggerable by a malicious peer via TCP urgent data on non-Linux systems (Windows and Mac nodes) — and an undo-file overflow a miner could trigger through a precisely timed reorg. Fixes shipped across four maintained branches at once (29.5, 30.4, 31.2, 32.1), per The Defiant. All three are denial-of-service class; no exploitation or fund risk is reported.
