The developers of Monero (XMR) have just disclosed that they have discovered and patched a critical bug that affects all CryptoNote-based cryptocurrencies, and allows for the creation of an unlimited number of coins in a way that is undetectable to an observer unless they know about the fatal flaw and can search for it. This major bug has been patched a while ago and it has been confirmed that the Monero network was never affected by it. All other active and affected CryptoNote coins, including CryptoNote themselves, Bytecoin, Forknote, Boolberry, DashCoin, and DigitalNote have apparently been notified about the possible issue prior to the public disclosure of the problem.

Note that, at this time, only Monero (XMR), Aeon (AEON), Boolberry (XBB), and Forknote have updated. This means that there could be potential abuse, though it may not necessarily happen with coins that have not patched and fixed the bug. As a result caution is advised for anyone using, trading, exchanging, or running services involving the following currencies affected by this issue: Bytecoin (BCN), DashCoin (DSH), DigitalNote (XDN). Just to clarify a possible misunderstanding by some users – DashCoin (DSH) is not the same as DASH as DASH is not CryptoNote, but X11-based!
