MS12-017: Vulnerability in DNS Server Could Allow Denial of Service (2647170) (uncredentialed check)

medium Nessus Plugin ID 72837
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The DNS server running on the remote host is susceptible to a denial of service attack.


According to its self-reported version number, the Microsoft DNS server running on the remote host does not properly handle objects in memory when looking up the resource record of a domain. By sending a specially crafted DNS query an attacker may be able to exploit this flaw and cause the DNS server on the remote host to stop responding and eventually restart.


Microsoft has released a set of patches for Windows 2003, 2008, and 2008 R2.
