Microsoft said it is still working on a fix for a broken patch released last Patch Tuesday that is causing Blue Screens of Death and system crashes. MS14-045 was released as part of the August 2014 Patch Tuesday security updates. It patched three vulnerabilities that could lead an attacker to elevate their privileges on a compromised Windows machine. Microsoft has provided a few temporary mitigations until the fix is fixed and re-released. The bugs affect Windows systems all the way back to Windows Server 2003 and all supported desktop versions of Windows.
