On July 7th I will be making public details of several serious denial ofservice vulnerabilities which have fixed in recent versions of Bitcoin Core,including CVE-2015-3641.I strongly recommend anyone running production nodes exposed to inboundconnections from the internet upgrade to 0.10.2 as soon as possible.Upgrading older systems, especially miners, is also important due to theBIP66 soft-fork which is about to reach enforcing status, see also:http://sourceforge.net/p/bitcoin/mailman/message/34199290/
