Risk: High
Microsoft identifies four important issues in July's Patch Tuesday.
Two of the four important flaws identified reside in Microsoft SQL Server and Outlook Web Access (OWA) for Microsoft Exchange Server. If successfully exploited, these vulnerabilities may lead to attackers gaining elevation of privileges.
One important issue has been identified in Windows Explorer, which may allow remote code execution when a specially crafted saved-search file is opened and saved.
The final flaw reported has been identified in Windows Domain Name System (DNS) that may result in a spoofing attack. These vulnerabilities exist in both the DNS client and DNS server.
