Microsoft · Windows Server · CVE-2017-0057
**Name of the Vulnerable Software and Affected Versions**
Microsoft Windows versions 8.1, 10 Gold, 10 1511, 10 1607, and Windows Server versions 2012 R2, 2016
Windows RT 8.1
**Description**
The issue is related to the DNS client in Microsoft Windows, which fails to properly process DNS queries. This allows remote attackers to obtain sensitive information by either convincing a workstation user to visit an untrusted webpage or tricking a server into sending a DNS query to a malicious DNS server. The vulnerability is associated with a lack of protection for service data.
**Recommendations**
For Microsoft Windows 8.1, update to a version that includes the fix for this issue.
For Windows 10 Gold, 1511, and 1607, update to a version that includes the fix for this issue.
For Windows Server 2012 R2 and 2016, update to a version that includes the fix for this issue.
For Windows RT 8.1, update to a version that includes the fix for this issue.
As a temporary workaround, consider restricting access to untrusted web pages and limiting DNS queries to trusted servers until a patch is available.
