02/10/2015

Jasbug, a Windows critical vulnerability reported in January 2014 that allowed remote execution of code, was patched one year later by Microsoft. This vulnerability affected all supported Windows versions since Windows Server 2003. Patching process took almost one year as it was not an implementation flaw, but a design one, so Microsoft had to re-design a part of Windows core.
