- An error in the Microsoft Server Message Block (SMB) Server when an attacker
with valid credentials attempts to open a specially crafted file over the SMB
protocol on the same machine.
- An error in the way that the Windows Kernel API enforces permissions.

objects in memory.
- Multiple errors leading to 'speculative execution side-channel attacks' that
affect many modern processors and operating systems including Intel, AMD, and ARM.
Vulnerability Impact:

to execute arbitrary code and take control of an affected system, elevate their
user rights, gain access to sensitive data, bypass certain security checks,
impersonate processes, interject cross-process communication, interrupt system
functionality and conduct bounds check bypass, branch target injection, rogue
data cache load.
Affected Software/OS:
- Microsoft Windows 7 for 32-bit/x64 Systems Service Pack 1
- Microsoft Windows Server 2008 R2 for x64-based Systems Service Pack 1
