Google has released details of a new privilege escalation bug in Microsoft’s Windows 8.1 operating system before Microsoft planned to patch the bug. This is second time in less than a month when the Google’s security research team known as Project Zero released details. Microsoft asked Google for an extension of the deadline till February 2015, when it plans to address the issue. Google refused to extend its 90-day public disclosure deadline even by two days, when Microsoft promised to fix the bug in January Patch Tuesday.
