This can enable an attacker to execute arbitrary commands as a legitimate user, potentially affecting the system. **Recommendations** For Microsoft Windows Server 2008 SP2 and R2 SP1, update to a newer version that includes the fix for this issue. For Microsoft Windows 7 SP1, update to a newer version that includes the fix for this issue. For Microsoft Windows 8.1 and RT 8.1, update to a newer version that includes the fix for this issue. For Microsoft Windows Server 2012 and R2, update to a newer version that includes the fix for this issue. For Microsoft Windows 10 versions Gold, 1511, 1607, 1703, and 1709, update to a newer version that includes the fix for this issue. For Microsoft Windows Server 2016, update to a newer version that includes the fix for this issue. For Microsoft Windows Server, version 1709, update to a newer version that includes the fix for this issue.
