A critical vulnerability affects the Windows and Samba implementations of the Server Message Block (SMB) protocol. The vulnerability was discovered by a core developer of the Samba software. The disclosure date coincides with Microsoft’s Patch Tuesday — the day when Microsoft releases its monthly security updates. Security experts say the disclosure of the bug’s existence, even without specific technical details, three weeks in advance has been criticized by some members of the security community because it gives potential hackers ample time to find it on their own.”]
