Microsoft Windows DNS Server Multiple Vulnerabilities

DNS NAPTR Query Vulnerability
A remote code execution vulnerability exists in the way that the Windows DNS Server improperly handles a specially crafted NAPTR query string in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in the context of the system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

DNS Uninitialized Memory Corruption Vulnerability
A denial of service vulnerability exists in the way that the DNS server improperly handles an object in memory that has not been initialized. An attacker that successfully exploited this vulnerability could cause the DNS server service on the target system to stop responding.
