Microsoft Corporation Information for VU#457875

Various DNS service implementations generate multiple simultaneous queries for the same resource record



Vendor Statement

The Microsoft DNS Server implementation closely follows the DNS standard. DNS is an insecure protocol and until such time as the protocol describes a method for securing queries, a determined attacker could poison the cache of a DNS Server. A number of precautions in the Microsoft DNS server make this style of attack more difficult, but not impossible. Microsoft is considering additional improvements to its DNS implementation in future versions of the Microsoft DNS sever to reduce the effectiveness of attacks like this.
